WP_Debug Log is a companion to WP_Debug that causes all errors to also be saved to a debug.log file. This is useful if you want to review all notices later or need to view notices generated off-screen. By default, this feature comes disabled. But you can enable this feature any time.

Enable Debugging Mode

  • Login to your Website's Cpanel. You might also access your account via SSH.
  • If you are using Cpanel, go to File Manager and open the file wp-config.php. But if you are using SSH, use a command prompt and open the wp-config.php file.
  • Add the following line of text to enable debugging mode – define(‘WP_DEBUG', true);
  • That's it, the Debugging mode is now enabled on your WordPress Website.
