WordPress includes several settings that you can use to help debug your site. These options are usually meant for developers, and you can turn it on by editing the wp-config.php file of your WordPress instance.

You need to login to your cPanel File Manager or FTP and edit the wp-config.php file, which should be available in WordPress instance’s root directly.

In wp-config.php file, file the following line:

define('WP_DEBUG', false);

And replace it with the following code:

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);

Save your wp-config.php file and you should be able to see your debugging logs in wp-content/debug.log anytime an error appears.

How to turn Off Debugging in WordPress:

It is just a difference of “true/false”. You will need to do the reverse of the above steps. In  wp-config.php file, find one or both of the following lines:

define('WP_DEBUG', true); 
define('WP_DEBUG_LOG', true);

Replace it with:

define(‘WP_DEBUG’, false);

Save your wp-config.php file.
