Getting Notice/Warning While Opening a Page

Sometime hosting companies force to show debug messages on site. You simply need to hide the message by adding 4 lines in wp-config.php (it's in root of your wordpress installation).

Just add these lines at the end of wp-config.php file, save it and reload the page where warning/notice was showing. It should be gone.

ini_set('display_errors','Off'); 
ini_set('error_reporting', E_ALL ); 
define('WP_DEBUG', false); 
define('WP_DEBUG_DISPLAY', false);
