WordPress журнал ошибок

No one likes to see errors on their website. Not only do they look bad to visitors and potential customers, but they also indicate that something’s wrong. But they’re, unfortunately, an inevitable part of running a site. The good news is that following a few best practices and being proactive can dramatically reduce the number of errors you experience. 

One way to monitor potential site issues — or troubleshoot existing ones — is to keep and review an error log. Let’s dive into this a bit more.

What is error logging and why is it important?

Error logging is the process of tracking and monitoring issues that occur on a website. This is usually done with a record of simple text files that live on your web server and are updated whenever an error occurs. Error logs are used to identify the number of problems that occur, provide details about each one, and show when it took place.

How to enable error logging

To enable error logging on your WordPress site, you’ll need sFTP access, available with WordPress.com plugin-enabled plans. This allows you to edit your website files remotely. In this case, you’ll be working with the wp-config.php file, which holds the basic configuration settings for your website.

A word of warning: you should only use sFTP and edit your wp-config.php file if you feel comfortable doing so. Mistakes can cause catastrophic errors on your website. If you don’t have experience changing these types of files, you may want to hire a developer or reach out to WordPress.com support for help.

1. Connect to your website via sFTP

You’ll need to start by enabling sFTP on your site. Go to My Site(s) → Settings → Hosting Configuration and click the Enable SFTP button.

Then, you’ll see your sFTP login details: URL, Port Number, Username, and Password. You’ll need to input these into FTP software, like FileZilla, to access your site. Follow these detailed instructions to connect to your WordPress.com website.

2. Find and download your wp-config.php file

Navigate to your wp-config.php file. This sits in the root directory of your file structure, alongside folders such as wp-content. Download this file, so you have a backup copy on hand.

3. Edit the wp-config.php file

Edit your wp-config.php file using a text editor such as Notepad.

Look for define( ‘WP_DEBUG’, false ); and replace this text with the following:

define( ‘WP_DEBUG’, true );

if ( WP_DEBUG ) {

        @error_reporting( E_ALL );

        @ini_set( ‘log_errors’, true );

        @ini_set( ‘log_errors_max_len’, ‘0’ );

        define( ‘WP_DEBUG_LOG’, true );

        define( ‘WP_DEBUG_DISPLAY’, false );

        define( ‘CONCATENATE_SCRIPTS’, false );

        define( ‘SAVEQUERIES’, true );

}

You’ve now successfully enabled error logging. You should only have this feature turned on while troubleshooting. Otherwise, it can leave your site more vulnerable to hacking attempts. To disable logging, simply delete the code you just added and restore the following:

define( ‘WP_DEBUG’, false );

How to view the error log manually

Once the log is enabled, you’ll need to load your website to trigger any error codes. Those codes are stored in a file called debug.log, which you can access via sFTP by following the same steps as above. 

You can find the debug.log file inside of the wp-content folder. If there are errors, the file will appear. However, if there aren’t any errors, then you won’t see it at all — congratulations!

Once you find the file, download it to your computer to view the full log, using a text editing software like Notepad. It will look something like this:

This file will provide valuable information that will point you, or your developer, to the source of your problem. 

How to view the error log using a plugin 

Using a plugin to find your error log can be an easier and faster method, depending on your level of experience. In the WordPress dashboard, click on Plugins → Add New. Search for “Error Log Monitor” and click Install → Activate.

This plugin installs a widget on your WordPress dashboard that allows you to access your error log. If you haven’t enabled error logging correctly, the widget will display instructions on how to do so. However, you should ignore these instructions, as they’re incorrect for a WordPress.com installation. Instead, use the ones listed above.

If you can’t see the dashboard widget, click on the Screen options tab at the top of the WordPress dashboard and ensure that “PHP error log” is checked.

How to find the plugin or theme that’s causing an error

Error logs are not inherently easy to read, but they do give insightful information into the cause of an error.

Typically, each line in your error log will display a message, alongside the date and time it happened and the file in which the error occurred. It also lists the line number where the error is located. For example:

Apr 20, 15:08:59

Notice: Undefined index: fg2 in /wordpress/themes/pub/varia/functions.php on line 166

Let’s break this down. First of all, there’s the date and time of the error: April 20, 15:08:59. This helps you determine if this was a one-off glitch or a recurring issue.

Then, you can see the type of error that’s been logged. Here are a few common types of error you may see here:

• Notice. These are more warnings than errors, as they don’t actually stop your website code from executing. While you should still address a notice, your site will most likely still function, although potentially not as designed.
• Parse error. This is typically the result of a mistake in the syntax of the underlying PHP code of the website (often in a theme or plugin). Parse errors include things like missing semicolons, parentheses, and other similar mistakes. A parse error will stop executing code when it hits the problem, so your site may look visibly broken or not function as intended.
• Fatal error. This is often caused by undefined functions or classes, like a typo or poor coding practice. You can avoid it by using high-quality code, along with functions such as class_exists or function_exists.

In this case, the error is a notice.

Next, we see the error itself. In the example above the error is “undefined index.” This is followed by the specific location of the problem. In the above example, the error is occurring with the functions.php file of the Varia theme.

How to fix errors

Now that you can see your errors, it’s time to troubleshoot. Here’s a few things you can try:

• If you’re a developer and the error is in your custom code, go to the line number in the log entry and work to debug.
• If the error is within a theme or plugin, start by checking for any available updates. Keeping your plugins and themes up to date is critical for avoiding bugs and maintaining website security. Once you’ve applied any updates, re-check the error log to see if there are any new entries. If the error still exists, reach out to the plugin author or consider switching to an alternative. 
• The error may also be caused by a conflict between two plugins. Try using the WordPress troubleshooting mode to fix this problem.
• If the problem occurred immediately after installing or updating a plugin, deactivate it to see if the error persists. If it doesn’t, the plugin is the likely cause and you may want to find an alternative. If the error occured after a core update, you may need to manually deactivate plugins to find the source.

Troubleshooting with the WordPress error log

WordPress, like any software, may occasionally run into problems. It may seem confusing to find and fix those problems, but the error log can be a huge help! It enables you to learn valuable information that can help you troubleshoot and solve site errors in a timely manner.

To avoid errors, always use well-maintained plugins and themes, and keep on top of updates. Need more help? If you have a WordPress plugin-enabled plan, you benefit from world-class Happiness Engineers that can provide guidance.

Диагностика проблем, возникающих на сайте WordPress, может оказаться сложной. Наглядный способ проследить появление ошибок и получить обратную связь – использование журнала логов. Изучение записей в логах позволит выяснить причину проблемы и устранить ее.

Где хранится лог ошибок ВордПресс и как его посмотреть

Первый шаг к исправлению ошибок на сайте – выяснить, при каких обстоятельствах они возникают. Кроме того, периодически могут появляться неявные ошибки и системные предупреждения, о которых вы не знаете, поскольку ваши действия их никогда не вызывали, но посетители сайта могли это заметить.

Чтобы просмотреть ошибки и предупреждения, необходимо записать их в специальный файл журнала. Ведение журнала логов является хорошей практикой, особенно если сайт находится в стадии разработки. Возможно, вам не удастся понять причину ошибки, когда она впервые возникнет, но как только вы получите больше информации при последующей работе, логи в журнале окажутся очень полезными для анализа ситуации.

Фактический журнал логов хранится в файле с именем debug.log в каталоге содержимого вашего сайта wp-content на сервере хостинг-провайдера. Как посмотреть логи? Один из способов просмотра и очистки журнала – прямой доступ к этому файлу. Скачайте файл с помощью файлового менеджера и откройте его любым текстовым редактором. Можно воспользоваться плагинами, которые упрощают работу с логами.

Можно ли удалять логи? Файл с отладочной информацией и уведомлениями об ошибках со временем может разрастись до внушительных размеров. Поэтому, если ваш сайт работает нормально, то старые логи можно удалить, чтобы освободить рабочее пространство.

Как включить/выключить логирование

Чтобы включить создание лог-журнала для сайта на WordPress, понадобится внести изменения в системный файл wp-config.php, который расположен на сервере хостинга.

1. Запустите файловый менеджер и подключитесь к удаленному серверу со своей учетной записью, который вам предоставил хостинг-провайдер.
2. Перейдите в корневой каталог, где установлен ваш сайт.
3. Сделайте резервную копию файла wp-config.php, чтобы восстановить систему после завершения отладки.

Откройте файл wp-config.php на удаленном сервере, вставьте или отредактируйте строки, которые управляют созданием логов:

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_DISPLAY', false );
define( 'WP_DEBUG_LOG', true );


Большинство сайтов на WordPress уже имеют запись для константы WP_DEBUG, установленную в значение false, поэтому вам нужно изменить это значение на true. Строка с WP_DEBUG_LOG может отсутствовать, поэтому придется ее добавить, эта команда активирует создание журнала логов для сайта. Константа WP_DEBUG_DISPLAY, установленная в значение false, поможет скрыть запись логов от посетителей сайта. Убедитесь, что каждая константа определена в файле только один раз.

Лог действий в WordPress

После того как запись логов включена, перейдите в папку содержимого сайта на WordPress. Обычно она называется wp-content, если вы не переименовали ее ранее. Откройте файл журнала debug.log, перейдите в конец и найдите строки с метками времени, соответствующими вашим недавним действиям над сайтом.

Каждый раз, когда возникает предупреждение или ошибка в работе сайта, WordPress генерирует уведомление, которое записывается в журнал логов с отметкой времени в формате UTC. По этим причинам на работающем сайте рекомендуется оставить WP_DEBUG включенным. Устраните выявленные проблемы, при необходимости восстановите оригинальный файл wp-config.php.

Ведение логов на сайте полезно, поскольку позволяет выяснить, какие именно действия вызывают ошибки, какие действия пользователей или администраторов сайта чаще всего провоцируют их возникновение. Кроме того, в логах фиксируется вся информация об изменениях на сайте, что позволяет отслеживать динамику сайта.

Плагины для логирования действий

Разработано несколько специальных плагинов, позволяющих просмотреть журнал логов напрямую из админки WordPress. Вы можете установить их прямо в админпанели в разделе «Плагины»

Activity Log – популярный плагин с большим количеством активных установок. Позволяет записать хронологию действий пользователей, их вход в админку и выход. Будут зафиксированы последние действия со страницами и записями, удаление и установка тем и плагинов.

WP Security Audit Log – плагин для мониторинга действий пользователей в админке сайта. Можно использовать для ведения лог-журнала электронного магазина WooCommerce и отслеживать изменение состояния продукта. Плагин создает предупреждение о безопасности, когда в системе создается новый пользователь, и позволяет отследить подозрительную активность, прежде чем это станет проблемой безопасности.

WP Log Viewer – плагин создает виджет панели администратора и позволяет включить/отключить запись лога одним щелчком мыши, при этом не требуется вручную редактировать файл wp-config.php. Можно выполнить фильтрацию ошибок, очистить журнал, сортировать записи по дате или провести поиск ошибок по времени. Пользовательские ошибки обозначаются разными цветами.

Error Log Monitor – этот плагин добавляет виджет, который видим только для администраторов. Он отображает последние сообщения из журнала логов, а также умеет отправлять уведомления по электронной почте о новых возникших ошибках. Частота уведомлений и количество отображаемых записей в журнале настраивается. Плагин оптимизирован для работы с очень большими лог-файлами.

For agency owners providing website development and maintenance services, encountering errors on clients’ websites can be challenging. Not only do errors create a negative impression for visitors and potential customers, but they also indicate that something is amiss.

It’s important to remember that no software is flawless, and problems or bugs may arise, especially when WordPress is enhanced with various themes and plugins.

Adopting best practices and taking a proactive approach is crucial to address these concerns and ensure smoother operations. One effective method to monitor and troubleshoot potential site issues is maintaining and reviewing an error log.

By configuring WordPress error logs in the wp-config file, agency owners can simplify the process of monitoring and diagnosing errors, thereby enhancing their website development and maintenance services.

In this article, I will guide you through the process of locating and accessing your WordPress error logs.

What Are WordPress Logs, and Why Are They Essential for Troubleshooting?

Error logging involves tracking and monitoring website issues by maintaining a record of simple text files on the web server. These files are updated whenever an error occurs, allowing for the identification and analysis of problems.

The error log comprises error messages, along with their respective dates and times of occurrence. By enabling WordPress debug mode, these messages are gathered in a file for future review.

WordPress error logs serve as a valuable troubleshooting tool, aiding in identifying problematic plugins, themes, or code. By examining the error logs, you can pinpoint common WordPress errors such as the WordPress White Screen of Death, 408 Request Timeout Error, or the SSH Connection Refused Error.

Now, let’s delve into the process of locating and accessing your WordPress error logs.

The initial step involves activating WordPress debug mode, which can be accomplished either through a plugin or by implementing specific code.

Method 1: Enabling WordPress Debug Mode with a Plugin

By default, WordPress does not enable error logging as debugging is turned off. To initiate error logging, the initial step is to install a WordPress debugging plugin such as the WP Debugging plugin or any other best WordPress debugging plugin.

Once you have successfully activated the plugin, it automatically enables WordPress debug mode, allowing error messages on your website to be recorded and logged for analysis and troubleshooting purposes.

Method 2: Enabling WordPress Debug Mode Using Code

If you are an advanced user, you can enable error logging and WordPress debug mode by modifying the wp-config.php file through sFTP access.

However, please note that this method requires caution, as making mistakes in the code can have severe consequences for your website.

1. Connect to Your Website via sFTP

To begin, enable sFTP on your site by navigating to My Site(s) → Settings → Hosting Configuration. Click on the “Enable SFTP” button. You will then receive your sFTP login details, including the URL, Port Number, Username, and Password. Use FTP software like FileZilla to connect to your site using these credentials.

2. Locate and Download the wp-config.php File

Find the wp-config.php file in the root directory of your website’s file structure, alongside folders such as wp-content. Download a copy of this file to create a backup.

3. Edit the wp-config.php File

Open the wp-config.php file using a text editor such as Notepad. Look for the line that says define(‘WP_DEBUG’, false); and replace it with the following code:

define('WP_DEBUG', true);

if (WP_DEBUG) {

        @error_reporting(E_ALL);

        @ini_set('log_errors', true);

        @ini_set('log_errors_max_len', '0');

        define('WP_DEBUG_LOG', true);

        define('WP_DEBUG_DISPLAY', false);

        define('CONCATENATE_SCRIPTS', false);

        define('SAVEQUERIES', true);

}

With these changes, error logging and WordPress debug mode will be enabled. Remember to keep this feature turned on only while troubleshooting, as leaving it active can potentially make your site more vulnerable to hacking attempts. To disable error logging, simply remove the code you added and restore the following line:

define('WP_DEBUG', false);

Accessing WordPress Error Logs

After enabling WordPress debug mode, you must load your website to trigger any error codes, which will be stored in a file called debug.log. To access this file via sFTP, follow the same steps mentioned earlier.

To locate the debug.log file, navigate to the wp-content folder. If there are errors, the file will be visible. However, if there are no errors, the file won’t appear at all, indicating that everything is working smoothly.

Once you find the debug.log file, download it to your computer. You can then open it using text editing software like Notepad to view the complete log. The log will contain valuable information that can help you or your developer identify the source of the problem.

Analyzing and Fixing Issues Found in WordPress Error Logs

The debug.log file provides valuable information about errors and warnings on your website but is not meant to be directly edited. Instead, you should use it as a reference to identify issues with your site, theme, plugins, or code.

To work with the debug.log file, follow these steps:

• Identify an error or warning in the debug log.
• Take note of the error code associated with the entry.
• Look up the meaning of the error code to understand the specific issue.
• Refer to separate guides or resources to find solutions for fixing that particular error.

When examining the debug.log file, each entry typically includes the date, time, module, process ID, and visitor’s IP address. However, the most important part is the error message itself. For example, you may encounter errors like “File not found,” indicating a missing file and providing its path.

Once you understand the cause of the error, you can proceed to fix it. Common solutions include updating links to files that have been moved or deleted.

Occasionally, you may encounter notice errors (e.g., “bot detected for vhost”), which indicate that the server closed the connection. The debug log should provide further details on why the connection was terminated, such as detecting a potentially harmful bot.

Remember that the debug.log file is primarily for troubleshooting purposes and should not be directly modified. It serves as a valuable tool for diagnosing and resolving issues on your website.

There are numerous types of WordPress error logs that one can encounter, and attempting to list all of them here would result in an extensive and exhaustive compilation.

But still, we can look at one example to see how one can look at error logs to identify and resolve performance-related issues.

For instance, permissions error…

A permissions error in the error log triggers a PHP warning. This type of error occurs when a file is being accessed with incorrect permissions.

One common scenario is when files are uploaded via SFTP without resetting the permissions through the wp-admin dashboard, resulting in incorrect permission settings. It’s important to verify the existence of the file mentioned in the error.

Example 1:

PHP Warning: The stream could not be opened for writing to the file "/path/to/yourblog/wp-content/themes/badperms/lib/css/theme.css" due to permission denied. This error originated in the file "/path/to/yourblog/wp-content/themes/WFTDAtv/lib/less/lessc.inc.php" on line 1418...

Example 2:

[Sat May 31 21:30:22 2023] [error] [client 127.0.0.1] PHP Warning: The stream could not be opened for writing to the file "/path/to/yourblog/wp-content/themes/yoo_phoenix_wp/cache/xml-80a72b04a693554d055946d5ad954588.php" due to permission denied. This error occurred in the file "/path/to/yourblog/wp-content/themes/yoo_regvis_wp/warp/helpers/xml.php" on line 34. Referring page: http://example.com/wp-admin/customize.php

In certain cases, such an error may indicate that a plugin or theme is attempting to perform an action that is not permitted or trying to access a file or directory that it should not have access to.

Example 3:

PHP Warning: Failed to open the stream for writing to the file "/path/to/yourblog/wp-content/cache/autoptimize/autoptimize_f7d7e4c8e9a3146b6b514d7e7f9e2468.php" due to permission denied. This error originated in the file "/path/to/yourblog/wp-content/plugins/plugin_folder/plugin_file.php" on line 22...

If you are trying to understand how the WordPress error logs works, you are in the right place! In this guide, we will cover all what you should know about it.

Monitoring PHP errors is something you need to do if you want to keep your WordPress website secure, healthy, and fast. If not fixed, PHP errors & warnings can indeed reduce your website performance and increase your website vulnerability to downtime and hackers.

The WordPress PHP Error Log can be your best friend in diagnosing various site issues. In this guide, we’re going deep into the subject — from how to enable PHP error logs to fixing the issues that arise.

We will also explain you how to implement a comprehensive PHP monitoring solution so you can be alerted when an error happens on your website.

Let’s get started!

What Are PHP Errors in WordPress?

PHP is the coding language WordPress is built on. When a user requests a web page that contains PHP code, the code is processed by the PHP module (Apache or Nginx) installed on the server.

Processing a request can generate PHP errors. This means that something is wrong with the PHP code. The error can be as simple as a missing semicolon, or as complex as calling an incorrect variable.

Note that, the most PHP errors that you can see on your WordPress site are usually warnings and notices. This being said, some of them (fatal errors, internal server error, etc) can stop your website from loading.

Here are The most frequent PHP errors you can encounter.

What Is a WordPress Error Log?

Indeed, even if your website seems to be working well, it may in fact be suffering from undetected PHP errors that should be fixed ASAP. The WordPress error log gives you the list of these errors.

Error logs provide you with information such as the error type, the error line, and the file concerned. You should use WordPress error logs to troubleshoot arising issues or understand why they’ve happened.

If the errors are coming from a third-party plugin, you should open a ticket on WordPress support forum.

Using WordPress Error Logs to Troubleshoot PHP Errors

If my explanation still looks blurry and if you don’t see the point of enabling the debugging mode for WordPress, here are some situations where you might really need it:

• When your WordPress website doesn’t load (blank page);
• When your web browser displays a warning with a PHP error code;
• If a plugin isn’t working properly;
• In case of downtime;
• If your website is really slow;
• If you want to improve your website performance & security;

How to Check PHP Error Logs in WordPress?

There are two ways to access PHP error logs in WordPress: manually or with a monitoring plugin. I’d personally advise to use WP Umbrella to monitor your PHP errors. It’s clearly the easiest way.

Monitor WordPress PHP errors logs with a plugin

Step 1: Get WP Umbrella Monitoring Plugin

WP Umbrella is a all-in-one solution to manage WordPress sites. It embed a PHP errors monitoring feature for WordPress.

WP Umbrella is interesting because it also checks your website’s uptime rate and provide you with automatic backups, security monitoring and much more..!

You need to install the plugin, create an account and connect your API key.

Step 2: Go to the PHP errors monitoring tab

Then, go to WP Umbrella’s application >> PHP issues.

From here, click on the “view error” to get all the information related to the PHP errors such as:

• The type of PHP error
• The plugin or theme responsible
• The environnement information (PHP version, plugin version, WordPress version)
• When the PHP error happened

That’s it, easy peasy!

Enable WordPress PHP Error Logs Manually

If you don’t want to use an error log plugin like WP Umbrella or Query monitor, you can enable WordPress error log and retrieve PHP errors from here.

Step 1: Access the wp-config.php file

The wp-config.php file contains important WordPress settings like how to connect to your database. This is the file you need to edit in order to enable WordPress debugging mode and access WordPress error logs where you will find your PHP errors.

First, you need to connect to your website using an FTP client. Then, download the wp-config.php file to make a backup of it. Then you can start editing it with your favorite HTML editor.

Step 2: Edit the wp-config.php file

Just before the line “That’s all, stop editing! Happy blogging” add this:

define( ‘WP_DEBUG’, true );
define( ‘WP_DEBUG_LOG’, true );

Or write true instead of false if the WP_debug function is already defined.

WP_DEBUG will allow you to enable debug mode and WP_DEBUG_LOG will allow you to send all errors to a file, so PHP errors are not displayed on your pages.

Save your changes and upload the file back to your website. The errors will then get logged to the debug.file within your wp-content folder. If you don’t see the file, you can create one.

This is where your WordPress error logs will be stored.
