 * I recommend doing the following:
    1. Navigate to the `public_html/wp-config.php` file.
    2. Please back up the original `wp-config.php` file (yes, it’s **absolutely** mandatory)
       in case something goes wrong so that you can restore it.
    3. Around line 81 you should see something like this:
 *     ```wp-block-code
       define( 'WP_DEBUG', true );
       ```
   
 * It might say `false` instead of `true`, but that doesn’t matter.
    4. You need to wrap this line like this:
 *     ```wp-block-code
       if ( ! defined( 'WP_DEBUG' ) ) {     define( 'WP_DEBUG', true ); // replace 'true' with 'false' as needed. }
       ```
   
    5. Save the file.
    6. Check if the issue is gone.
 * If that doesn’t resolve the issue, you’ll need to disable your plugins to see
   if any particular plugin is causing problems. Please refer to [this guide](https://wordpress.org/support/article/faq-troubleshooting/#how-to-deactivate-all-plugins-when-not-able-to-access-the-administrative-menus)
   on how to do it.
 * Let me know if you need further assistance!

 * FWIW, `WP_DEBUG` should never be defined as `true` on a production site unless
   you’re actively developing code on it. And it’s not a great idea to develop code
   on a production site anyway. Development should be done on staging or local installations.

   Thanks Anton and bcworkz!
