Edit wp-config

This step involves pasting a single PHP line into the wp-config.php file. Add the following line at the bottom of the file:

define(‘CONCATENATE_SCRIPTS’, false);

This line disables the concatenation of script files. By default, WordPress attempts to optimize the admin dashboard by combining JavaScript files into one file. This can enhance loading speed and reduce server requests, generally improving performance.

However, in certain situations, this optimization can cause issues. Conflicts between scripts or compatibility issues with specific scripts may lead to functionality errors or degradation in the admin panel.

If you’re experiencing conflicts from various plugins, adding this PHP code snippet might help resolve the editor error.

Alternatively, if you’ve identified the conflicting plugins, consider contacting their developers. Reporting the issue may prompt them to address any bugs, potentially resolving the problem without the need for PHP modifications.

  • Go to Plugins ⟶ Add New Plugin.
  • Search for “Classic Editor” in the plugin directory.
  • Install and activate the Classic Editor plugin.
  • Once activated, the next time you create a post, you’ll find yourself back in the familiar Classic Editor interface.

FAQs About “the Editor Has Encountered an Unexpected Error” Issue in WordPress

How to fix “An unexpected error has occurred”?

This generic error can appear in several areas of your WordPress website, especially in the admin panel or editor. It’s often linked to plugin conflicts, JavaScript issues, or failed updates.

Here’s what you can do:

  • Reinstall WordPress Core Files: Go to Dashboard Updates and click “Re-install Now.” It won’t delete your content, but can fix any corrupted core files.
  • Update WordPress Core and Plugins: Outdated software can clash with the modern WordPress block editor. Make sure everything’s up to date.
  • Deactivate the Last Plugin You Installed: Start by disabling the last plugin you added or updated. Many unexpected errors come from one faulty plugin.
  • Enable WP_DEBUG: Add define(‘WP_DEBUG’, true); in your wp-config.php file. This will display more detailed error messages, helping you pinpoint the issue.

How to fix the critical error in WordPress?

A critical error in WordPress typically means something has gone wrong at the server or code level, often after installing a new plugin, theme, or update.

To fix it:

  • Check for PHP Version Conflicts: Ensure your hosting environment uses a compatible PHP version for your WordPress setup and plugins.
  • Enable Recovery Mode (Check Your Email): WordPress will send a link to your admin email allowing you to log in and deactivate problematic features.
  • Use FTP or File Manager to Deactivate Plugins: Go to wp-content/plugins/ via FTP and rename plugin folders one by one. Start with the last plugin you installed or updated.
  • Switch to a Default Theme: Temporarily change your theme via FTP or your hosting panel to rule out theme-related issues with the visual editor or block editor.
  • Reinstall WordPress Core: Re-downloading the latest version and replacing core files can often fix corruption-related errors without touching your content.

How to fix “The application has encountered an unexpected error”?

If this message pops up while using a plugin, theme, or a third-party app integrated with your WordPress website, it typically points to a compatibility or server issue.

Steps to troubleshoot:

  • Contact Plugin Support: If the error is coming from a specific tool (like a page builder or form plugin), reach out to the developer’s support team with a screenshot and error details.
  • Isolate the Source: Did you recently activate a new plugin or theme? Try rolling back or deactivating the last plugin to see if the error goes away.
  • Check Server Logs: If you have hosting access, review your error logs. They’ll often tell you what part of the application (plugin, theme, etc.) triggered the issue.

How to fix “The editor has encountered an unexpected error” in WordPress?

This common error usually shows up when there’s a conflict inside the WordPress block editor (also known as Gutenberg). It can be frustrating, especially when you’re trying to publish content quickly on your WordPress website.

Here’s how to fix it:

  • Clear Browser and Site Cache: Sometimes caching plugins or your browser’s cache can interfere with the block editor. Clear both to rule out caching as the cause.
  • Switch to a Default Theme: Temporarily switch to a default WordPress theme like Twenty Twenty-Four. If the error disappears, your theme may not be fully compatible with the block editor.
  • Disable Plugins One by One: This error is often caused by plugin conflicts. Start by deactivating different plugins, especially the last plugin you installed or updated. After each deactivation, check if the editor works again.
  • Use the Classic Editor Plugin: If you’re on a tight deadline, consider installing the Classic Editor plugin to replace the visual editor temporarily. This lets you continue working while you troubleshoot the main issue.
  • Check Browser Console for Clues: Press F12 or right-click ⟶ Inspect ⟶ Console tab. This may reveal the specific script or plugin causing the issue.
