By default, there is no built-in option to disable admin notification after user registration. You can use the following function code. Please see the steps below:
1. Navigate to WordPress dashboard – Appearance – Theme Editor.
2. Under Select theme to edit, choose (BuddyBoss Child/whatever theme is active), then click Select.
3. Below Theme Files, select Theme Functions (functions.php).
4. Append the code just before the closing PHP tag “?>”:
remove_action('register_new_user', 'wp_send_new_user_notifications');
remove_action('edit_user_created_user', 'wp_send_new_user_notifications', 10);
add_action('register_new_user', 'bb_wp_send_new_user_notifications', 10, 2);
add_action('edit_user_created_user', 'bb_wp_send_new_user_notifications', 10, 2);
function bb_wp_send_new_user_notifications($user_id, $notify = 'user') {
switch ($notify) {
case 'admin':
$notify = 'none';
break;
case 'both':
$notify = 'user';
break;
}
wp_new_user_notification($user_id, null, $notify);
}
5. Click Update File to save the changes.
