            public function online_users($return='count'){
                $override = apply_filters('pre_nebula_online_users', null, $return);
                if ( isset($override) ){return;}
                $logged_in_users = $this->get_data('users_status');
                if ( empty($logged_in_users) || !is_array($logged_in_users) ){
                    return ( strtolower($return) === 'count' )? 0 : false; //If this happens it indicates an error.
                $user_online_count = 0;
                $online_users = array();
                foreach ( $logged_in_users as $user ){
                    if ( !empty($user['username']) && isset($user['last']) && $user['last'] > time()-600 ){
                        $online_users[] = $user;
                return ( strtolower($return) === 'count' )? $user_online_count : $online_users;


    To override this PHP function, use this hook in your child theme or plugin ("my_custom" can be changed):

    add_filter('pre_nebula_online_users', 'my_custom_online_users', 10, 2); //The last integer must be 1 more than the actual parameters
    function my_custom_online_users($null, $return){ //$null is required, but can be ignored
        //Write your own code here
        return true; //Return true to prevent the original function from running afterwords

    You can completely disable this PHP function with a single line actions:

     add_filter('pre_nebula_online_users', '__return_false');
