I have seen a few posts in these forums looking for a way to disable PHP notices or to disable php warnings showing up in WordPress.
The other posts suggested putting the following at the *top* of wp-config.php file:
This does not work, however, because when that file calls wp-settings.php at the bottom, the error reporting is overidden by WordPress' own settings.
In order for the line above to work, it most come after the call to wp-settings.php - for example:
/** Sets up WordPress vars and included files. */ require_once(ABSPATH . 'wp-settings.php'); error_reporting(0);
Just remember, if you want to enable WP_DEBUG, you will have to comment out this line for you to see debugging errors.
Hope this helps!
