To enable debug mode in WordPress, first go to cPanel and open File Manager. Navigate to your domain's root folder and open wp-config.php. Find a line that looks like:
define( 'WP_DEBUG', false );
And change it to:
define( 'WP_DEBUG', true );
Now your website will show you what's wrong with it. After you are done debugging, don't forget to set it back to:
define( 'WP_DEBUG', false );
to make sure nobody will see your website errors, warnings, or other sensitive information.
