Hi @alber,

Yes, you should put this custom code in your current active WordPress functions.php file:

function my_custom_foro_notifications_filter( $args ){
   if( !empty($args) ){
      $args['types_exclude'] = array('new_like', 'new_up_vote', 'new_down_vote');
   }
   return $args;
}
add_filter('wpforo_get_notifications_args', 'my_custom_foro_notifications_filter', 10, 1);
