You're right. Try this for the beginning of the code:

<?php 
$specialtemplates = array('userstats');
chdir('./forum');
require_once('./global.php');
cache_ordered_forums(1, 1);

If you wanted you could chdir() to the absolute path instead. And also you could save the current directory and chdir back after including gobal.php, but if that's the entire code then it doesn't look like it's necessary.
