Resolving WordPress Critical Errors

Encountering a critical error on your WordPress website can be unnerving, but fear not. In this comprehensive guide, we’ll walk you through the steps to effectively diagnose and resolve these errors, ensuring your website gets back on track quickly.

Method 1: Deactivating Recently Added Plugins or Themes

Step 1: Access Your WordPress Dashboard

Log in to your WordPress admin dashboard. If you’re unable to access it due to the critical error, you can use an FTP client to connect to your site’s files.

Step 2: Deactivate Plugins

Go to the “Plugins” section and deactivate all recently added or updated plugins. This can help identify if a plugin is causing the error.

Step 3: Check Your Site

After deactivating the plugins, refresh your website. If the critical error is resolved, reactivate the plugins one by one to pinpoint the problematic one.

Step 1: Access Your Hosting Control Panel

Log in to your hosting control panel (cPanel, Plesk, etc.) and navigate to the backup section.

Step 2: Choose a Backup

Select a backup created before the critical error occurred. Make sure to choose a complete backup, including your website files and database.

Step 3: Restore the Backup

Follow your hosting provider’s instructions to restore the chosen backup. This process may take a while, so be patient.

Step 4: Verify the Site

After the restoration is complete, check your website thoroughly to ensure the WordPress critical error is resolved. If successful, take precautionary measures to prevent the error from happening again.

Method 3: Debugging Using WP_DEBUG

Step 1: Enable WP_DEBUG

Access your site’s files using an FTP client. Look for the wp-config.php file and open it for editing. Add the following line of code just above the line that says “That’s all, stop editing! Happy blogging.”:

define(‘WP_DEBUG’, true);

Step 2: Check for Errors

Visit your website. Instead of the critical error message, you’ll see specific error messages that can help you identify the issue.

Step 3: Note the Errors

Take note of the errors displayed. They might point to a specific file, plugin, or theme causing the problem.

Step 4: Resolve the Issue

Based on the error messages, you can take appropriate action. It might involve editing a specific file, replacing a plugin, or contacting a developer for assistance
