Problem with functions.php

[badpacket]

Fatal error: Call to undefined function: fetch_user_location_array() in /home/dafreak/public_html/community/includes/functions.php on line 944

I've installed a few hacks, but when i try to view a users profile i get that error.. I really dont know where to look to fix it.. any help would be appreciated..

btw my like 944 in functions php is -

if ($option & 4)
{ // Process Location info for this user
require_once('./includes/functions_online.php');
$user = fetch_user_location_array($user); <- line 944
}
