PHP warnings and errors are different. When PHP errors crash or break the site the PHP warnings just display some annoying error reports. We can easily disable PHP warnings on the WordPress website.
Here is an example of a PHP warning. If you see something like this then I will show you how to hide the warnings.
Open the wp-config.php and find the line
/* That's all, stop editing! Happy publishing. */
Add this code before that line.
define( 'WP_DEBUG', false ); ini_set('display_errors','Off'); ini_set('error_reporting', E_ALL ); define('WP_DEBUG_DISPLAY', false);
It will disable the PHP warnings from your WordPress website.
