[SOLVED] Call to undefined method?

[darkfreaks]

how would i fix this problem? the last problem i fixed by adding inlude_once(includes/header2.php).

 

but now i get undefined method Security->online_users;

 

Code:

<?php
$qls->Security->online_users;?>

[darkfreaks]

ok i tried

 

<?php

$users = $qls->Security->make_safe->online_users();?>

 

now i get call to a non object again? but the header2 file is included?
