Errors should normally be good for telling you something went wrong
But if you really want, due to some special purposes, to hide Php errors in WP, then
Open Your wp-config. php File.
Replace the Debug Lines. Replace the existing lines with the following code snippet:
ini_set('display_errors','Off');
ini_set('error_reporting', E_ALL );
define('WP_DEBUG', false);
define('WP_DEBUG_DISPLAY', false);
Save and Upload.
Alternatively, if you can access the php.ini file, then use the following line (restart your httpd after changing the ini file):
display_errors = On
