Can’t Disable New User Admin Notification

Hi all,

I’m attempting to kill new user notifications that are going to the admin. I’ve used a couple of plugins, as well as a custom function that did not work.

I’ve tried:

https://www.ads-software.com/plugins/manage-notification-emails/
https://www.ads-software.com/plugins/disable-new-user-notifications/

Function:

if ( !function_exists('wp_new_user_notification') ) {

    function wp_new_user_notification( ) {}

}

I’m wondering if anyone else has had an issue with this notification disabling? Thanks in advance!
