Client Problem: The website loads as a completely blank white screen with no error messages or content displayed.

Cause: A critical PHP code crash caused by an incompatible plugin update, broken theme code, or syntax error that suppresses error output.

Technical Solution Steps:

1. Log in to cPanel: Access your cPanel account using your credentials.

2. Enable WP Debug: Go to files section then open File Manager > public_html,  then go to wp folder,edit wp-config.php, and change define('WP_DEBUG', false); to define('WP_DEBUG', true);.

   
   

3. Check Display Errors: In cPanel, navigate to Software > MultiPHP INI Editor, select your domain, and set display_errors to On to view the exact failing script.

   
   

4. Deactivate Faulty Plugin: Open File Manager > public_html/wp-content/plugins, find the folder of the plugin named in the error message, and rename it (e.g., plugin-name_old).

5. Test and Disable Debug: Reload the website to confirm it works, then change WP_DEBUG back to false in wp-config.php
