How to hide php errors in Wordpress?

Question

WordPress

site/wp-content/plugins/contact-form-7/modules/submit.php - when accessing this path, it gives errors like (Fatal error: Call to undefined function add_action() in)
How can they be hidden in WordPress?
Tried

ini_set('log_errors','On');
ini_set('display_errors','Off');
ini_set('error_reporting', E_ALL );
define('WP_DEBUG', false);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);

Doesn't help

Answer 1

E_ALL does not hide, but on the contrary, displays everything.
php.net/manual/ru/function.error-reporting.php
in the theme header or in functions.php
You can selectively, for yourself, in order to notice or not forget in time:

is_admin() ? error_reporting(E_ALL) : error_reporting(0);

Answer 2

And I would advise you to correct the error, and not hide it ...
