WordPress users may encounter this ominous message: “A critical error has occurred on this website.” It can appear without warning—your website suddenly disappears, and you have no idea why. Still, don’t panic! This is a common issue, and you can fix critical error problems in WordPress with the right steps. Let’s walk through the instructions to restore your site.

What does this error mean?

Commonly, this error indicates that there was an error with the code of your WordPress site. It might be caused by:

  • A broken plugin or theme
  • An argument involving plugins
  • An unwelcome update
  • PHP or server problems

WordPress displays a generic message rather than the whole error when this occurs. This guards your site from presenting delicate information.

Step 1: Set Debug Mode to Enabled.

More specifics are needed to find the real problem.

  • Debug mode may be enabled as follows:
  • Open the file wp-config.php.
  • Look for these lines:
define(‘WP_DEBUG’, true);

define(‘WP_DEBUG_LOG’, true);

define(‘WP_DEBUG_DISPLAY’, false);
  • Alter it, keep the file.

This will generate a debug log under wp-content/debug.log. Examine this file for the precise reason.

Step 2: Turn off every plugin

Frequent causes are damaged plugins. To turn off every plugin:

  • Open your hosting file management or FTP.
  • Visit wp-content/.
  • Rename the plugin directory to plugins_old.
  • This will deactivate all plugins. Visit your website once more now. The plugin was the issue if it was loaded.
  • To determine which one:
  • Change plugins_old back to plugins.
  • Check your site following every activation till it breaks again.
  • You now understand the defective plugin. Either get rid of it or switch it off.

Step 3: Choose a Basic Theme

  • The theme occasionally gives rise to the fault.
  • Find your FTP and look for wp-content/themes/.
  • Rename your active theme directory (e.g., mytheme_old).
  • WordPress will now work on an incorrect theme like Twenty Twenty-Four.
  • Check your website's functioning. Yes, there is a problem. It may be swapped or reinstalled.

Step 4: Verify the PHP Version and Memory Limit

  • This mistake could arise from low memory or old PHP.
  • Visit your hosting control panel.
  • Increase PHP memory limit in wp-config.php:
  • Reload your website after saving the file.

Step 5: Return a Backup

Use a backup. Many hosts provide automatic backups. Plugins like UpdraftPlus or Jetpack also let you use them.

Return your site to the most recently functional version. Then start fixing from there.

Step 6: Get in touch with your hosting company.

  • If you are caught, call your host. They might assist you with:
  • Examine server logs.
  • Fix PHP bugs.
  • Regain your website.
  • Most hosting providers are willing to help with such problems.

Last Tips

  • Update your plugins and themes regularly.
  • Only employ trusted tools.
  • Always back up your website before major changes.,
