[Feoni]

I can't even seem to install it. I tried to do the first part of finding the forum path but it says
<?php

if ($_SERVER['PATH_TRANSLATED'])
{
$path = $_SERVER['PATH_TRANSLATED'];
}
else if ($_SERVER['SCRIPT_FILENAME'])
{
$path = $_SERVER['SCRIPT_FILENAME'];
}
else
{
echo 'We are sorry, but this script is unable to determine your forums path.';
exit;
}

echo substr($path, 0, (strlen($path) - 14));

?>
so im lost please help

Did you upload that file to your vBulletin folder on your server and then go to it in your browser?
