What are WordPress Fatal Errors?

WordPress Fatal Errors occur when a critical issue prevents WordPress from functioning correctly. As a result, the site becomes inaccessible to visitors and administrators. 

Typically, these errors occur due to conflicts between themes, plugins, or server misconfigurations. 

For example, if you’re trying to reach your admin, and your site has fallen victim to a fatal error, it will look something like this:

What are the Most Common Types of WordPress Fatal Errors?

The most common types of fatal errors include:

• PHP Errors: Faulty PHP code, such as syntax errors, can cause fatal errors for a site.
• Memory Limit Exhaustion: You can also get this error if a script exceeds the memory limit.
• Plugin/Theme Conflicts: Sometimes, incompatible or poorly coded plugins or themes may also cause fatal errors.
• Missing/Corrupted Files: WordPress shows a fatal error when core files, themes, or plugins are missing or corrupted.
• Database Connection Issues: If your WordPress site fails to connect to the database, you will see this error.

8 Solutions to Access WordPress Admin with a Fatal Error Warning

Use these eight solutions in order to get back into WordPress admin after a fatal error.

1. WordPress Recovery Mode

WordPress now automatically detects when your site encounters plugin or theme conflicts. To help you resolve the situation, WordPress sends an error log and recovery mode link to the site admin email. 

So, if you’re locked out of your WordPress site due to a critical error, WordPress will activate Recovery Mode. You’ll receive an email with a recovery link to access the site and fix the issue without accessing the backend directly.

Here is what one of these emails looks like:

Select the recovery mode. Then, deactivate the plugin or theme that caused the problem. 

You’ll regain access to your site once you deactivate the plugins or themes that caused trouble. 

If it doesn’t work, try the other steps on this list.

2. Deactivate All Plugins

Didn’t receive a WordPress recovery email? You can deactivate all WordPress plugins instead. 

Since you’re logged out of WordPress admin, you can access your WordPress site using FTP (File Transfer Protocol). 

You need to log into your FTP, go to the file manager, and navigate to the wp-content/plugins directory.

Next, rename the plugins folder. 

This automatically deactivates all the plugins on your site.

Now, try to log into your site. If you succeed, one of your plugins caused the fatal error.

Next, you can reactivate each plugin individually to identify the conflicting plugins. 

3. Switch to a Default WordPress Theme

If the issue persists after deactivating plugins, try switching to a default WordPress theme like Twenty Twenty-Five. 

This will help determine if the issue lies within your theme.

Go to FTP or your hosting control panel to access the wp-content/themes directory. 

Next, rename your active theme’s folder. Doing so deactivates the theme, which should restore access to your site.

4. Check for PHP Errors

Errors in PHP files can also cause the site to display fatal errors. 

Remember, PHP errors appear when there is a syntax fault or a resource limit is reached. They could also result from conflicts inside your WordPress code. 

You can check for PHP errors by enabling WP_DEBUG in your wp-config.php file. This will help identify any coding issues causing the problem.

To resolve this issue, you must log into your WordPress files via FTP. Next, search for the wp-config.php file in the root directory of your WordPress installation.

Now, download the file or edit it directly.

Add the following PHP code to the end of the line:

PHP

define('WP_DEBUG', true);

define('WP_DEBUG_DISPLAY', true);

define('WP_DEBUG_LOG', true);

It will create a debug log file (debug.log) for you in the wp-content folder. This log file has detailed information about the errors, such as:

• Error messages
• Line numbers
• File locations

You can use it to identify the source of the error. You can start troubleshooting once you identify the PHP error causing the fatal error.

Note: If you’re not comfortable debugging WordPress files, it is better to hire a developer.

5. Check for Malware

Malware can also crash your WordPress site.

So, it is always better to have a security plugin, such as Wordfence or Sucuri, installed and activated on your site. 

Note: If you want to select a WordPress security plugin for your site, see our detailed guide on 9 Best WordPress Security Plugins.

These plugins scan your site for malware on an ongoing basis. Plus, you can schedule scanning at regular intervals.

This is how you can stay informed about your site’s health and promptly remove malware if detected.

6. Clear Your Site Cache

Cached versions of your site may still show errors or old content. 

Clear your WordPress site’s cache (if you use a caching plugin) and your browser cache, so you see the latest version of the site.

To clear your site cache, access your site’s root directory from your hosting control panel.

Next, open wp-content and delete the cache folder and the advanced-cache.php file.

Now, it’s time to clear your web browser’s cache. When done, reload the page and check if the error persists.

7. Restore from Current Backup

If troubleshooting isn’t resolving the fatal error, restore your site from the most recent backup. 

Many hosting providers offer automatic backups for emergencies. Choose one that offers daily automatic backups.

If you lose data, you can restore it to its most recent state.

All you need to do is to log into your hosting provider and go to the backup option.

Note: If you want to choose the best hosting provider with backup options, see our detailed guide on best WordPress hosting providers.

For example, SiteGround offers automatic backup. You can use these backups to restore your site altogether. Even if you have multiple sites on this server, you can back up and restore them with just a single click.

 You can also back up selected parts of your site, such as:

• Files
• Databases
• Emails

Other than daily backups, SiteGround offers manual and hourly backups, plus backup downloads.
