Assistant

This error occurs because Elementor Pro is trying to load a class that is either missing or incorrectly defined. It often happens due to:

1. **Incomplete Plugin Installation/Update**: The Elementor Pro plugin may not have been installed or updated properly.

2. **Version Mismatch**: There might be a mismatch between Elementor (free version) and Elementor Pro. Both plugins should be updated to compatible versions.

3. **Corrupt Plugin Files**: Files in the Elementor Pro plugin may be corrupted.

4. **Conflicting Plugins or Themes**: Other plugins or themes might conflict with Elementor Pro.

Here’s how to fix it:

—

### 1. **Verify Plugin Version Compatibility**
– Check the version of Elementor (free) and Elementor Pro installed on your site.
– Visit Elementor's [version compatibility table](https://elementor.com/help/version-compatibility/) and ensure both versions are compatible.
– Update both plugins if necessary:
– **Free Version**: Update via the WordPress plugin repository.
– **Pro Version**: Download the latest version from your Elementor account and upload it via the WordPress admin or FTP.

—

### 2. **Reinstall Elementor Pro**
– Deactivate Elementor Pro in your WordPress admin under **Plugins**.
– Delete Elementor Pro (**data won’t be lost**).
– Download the latest version of Elementor Pro from your Elementor account.
– Reinstall and activate it.

—

### 3. **Check for Missing Files**
– Verify that the required file `/core/app/modules/site-editor/data/controller.php` exists in the Elementor Pro plugin folder.
– If missing, replace the entire Elementor Pro folder with a fresh download.

—

### 4. **Debug Conflicts**
– Temporarily deactivate all other plugins except Elementor and Elementor Pro.
– Switch to a default theme like Twenty Twenty-Four.
– Check if the error persists. If resolved, activate plugins one by one to identify the conflict.

—

### 5. **Enable Debugging for More Insight**
Add the following lines to your `wp-config.php` file to get detailed error logs:

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

After reproducing the error, check the debug log in `wp-content/debug.log` for more clues.

—

### 6. **Check File Permissions**
Ensure the Elementor Pro plugin files have proper permissions:
– Directories: `755`
– Files: `644`

—

### 7. **Contact Elementor Support**
If none of the above works, contact Elementor Pro support and share the error details. They might need your system info and a copy of your site for troubleshooting.

Let me know if you need help with any of these steps!
