how to access wordpress admin with a critical error warning

WordPress / By

If you’re seeing a “Critical Error” warning on your WordPress site and are unable to access the admin dashboard, it can be a daunting issue to resolve. However, there are several ways to troubleshoot and regain access to your WordPress admin area. Below are the steps you can follow to troubleshoot and fix the issue.

1. Enable Debugging to Identify the Error

The first step in troubleshooting is to identify the exact error that’s causing the issue. WordPress has a debugging feature that can help.

Steps:

  1. Access your wp-config.php file:
    • Use FTP (FileZilla) or your hosting provider’s file manager to locate and open the wp-config.php file in the root directory of your WordPress installation.
  2. Enable Debugging:
    Add the following code before the line that says “That’s all, stop editing!”: define( 'WP_DEBUG', true ); define( 'WP_DEBUG_LOG', true ); define( 'WP_DEBUG_DISPLAY', false ); This will log errors to a file called debug.log in the wp-content folder, without displaying errors to users on the front end of your website.
  3. Check the debug.log file:
    • After enabling debugging, try accessing the admin area again and check the wp-content/debug.log file to identify the error causing the critical issue.
    • Once you know the error, you can work on fixing it (e.g., plugin conflict, memory limits, etc.).

2. Access the Admin Dashboard via the Recovery Mode Link

Since WordPress 5.2, WordPress offers a recovery mode feature that helps you regain access to the admin panel in case of a critical error.

Steps:

  1. Check your email:
    WordPress will send you a recovery mode link to the admin email address registered with your site. The email will contain a link that allows you to log in even if a critical error is preventing access.
  2. Click on the recovery mode link:
    Click the recovery link in the email, and you’ll be redirected to a page where you can log into your WordPress dashboard.
  3. Deactivate plugins or themes causing issues:
    After logging into the recovery mode, you’ll be able to see the problematic plugin or theme that triggered the critical error. Deactivate the plugin or theme causing the issue and check your site again.

3. Deactivate Plugins via FTP or File Manager

A plugin conflict or an issue with a plugin can cause a critical error. If you’re unable to access the WordPress admin dashboard, you can manually deactivate plugins using FTP or the file manager.

Steps:

  1. Access your website files via FTP or File Manager:
    Use FTP (FileZilla) or your hosting file manager to connect to your site’s files.
  2. Navigate to the wp-content folder:
    Open the wp-content folder and then go to the plugins folder.
  3. Rename the plugins folder:
    Rename the plugins folder to something like plugins_old. This will deactivate all plugins on your site.
  4. Check the admin dashboard:
    After renaming the folder, try accessing your WordPress admin panel again. If the issue was caused by a plugin, you should now be able to access the dashboard.
  5. Reactivate plugins one by one:
    • Go back to the plugins folder and rename it back to plugins.
    • Reactivate plugins one by one by renaming the plugin folders back to their original names until you find the plugin causing the error.
    • Once identified, you can either update, delete, or troubleshoot that plugin.

4. Switch to a Default WordPress Theme

Sometimes a problematic theme can cause critical errors. If the issue is theme-related, you can switch to a default WordPress theme using FTP or the file manager.

Steps:

  1. Access your website files via FTP:
    Use FTP (FileZilla) or your hosting file manager to access the files.
  2. Navigate to the wp-content/themes folder:
    Go to the wp-content/themes folder where your active theme is located.
  3. Rename your active theme folder:
    Rename the folder of your active theme (e.g., twentytwentyone) to something else, like twentytwentyone_old.
  4. WordPress will fall back to a default theme:
    After renaming the folder, WordPress will automatically switch to one of the default themes like Twenty Twenty-One or Twenty Twenty-Two. Try accessing the admin dashboard again.

5. Increase PHP Memory Limit

A memory limit issue can also cause a critical error in WordPress. If your site is running out of memory, it can trigger this error.

Steps:

  1. Edit your wp-config.php file:
    Use FTP or file manager to open the wp-config.php file in your root WordPress directory.
  2. Increase the memory limit:
    Add the following line to the file before the “That’s all, stop editing!” line: define( 'WP_MEMORY_LIMIT', '256M' );
  3. Save and check your site:
    After saving the changes, try accessing your WordPress dashboard again.

6. Reinstall WordPress Core Files

If the above methods don’t work, your WordPress installation may have corrupted files. You can reinstall the core WordPress files manually or through the dashboard.

Steps (through Dashboard):

  1. Go to Dashboard > Updates:
    If you can access the admin dashboard, go to Dashboard > Updates.
  2. Reinstall WordPress:
    Click the Reinstall Now button to reinstall the latest version of WordPress. This will not affect your posts, pages, or settings, but it will replace any corrupted core files.

Steps (manually):

  1. Download the latest WordPress version:
    Go to wordpress.org and download the latest version of WordPress.
  2. Upload files:
    Extract the downloaded files and upload the wp-admin and wp-includes folders to your server via FTP, replacing the old ones.
  3. Check your site:
    Once the core files are replaced, check if the critical error has been resolved.

7. Check for Server-Side Issues

If none of the above steps work, the issue could be server-related. Your hosting provider may be experiencing issues with their server or database. Contact your hosting provider’s support team to check if there’s a server-side issue causing the critical error.

Conclusion

The “Critical Error” in WordPress can be caused by various issues, such as plugin conflicts, theme problems, or server misconfigurations. By following the steps above, you should be able to troubleshoot and resolve the issue.

Remember to always back up your website before making any changes. If the issue persists or you’re unable to pinpoint the cause, don’t hesitate to reach out to your hosting provider or a WordPress professional for further assistance.
