Reset Notices

[chrissyplum79]

I am trying to reset notices I removed on my forum I have a code here:

PHP Code:

<?php
if ($_COOKIE['bbuserid']==0 || $_COOKIE['bbuserid']==null)
{ die('You must be logged in to reset dismissed notices.'); }
include('includes/config.php');
$servername = $config['MasterServer']['servername'];
$port = $config['MasterServer']['port'] ? $config['MasterServer']['port'] : 2082;
$con = mysql_connect("$servername:$port",$config['MasterServer']['username'],$config['MasterServer']['password']);
mysql_select_db($config['Database']['dbname'], $con);
mysql_query("DELETE FROM tta_noticedismissed WHERE userid=" . intval($_COOKIE['bbuserid']));
mysql_close($con);
echo '<script type="text/javascript">
<!--
window.location = "http://toontownmania.com/forums/"
//-->
</script>';

?>

I am currently running on vBulletin 4.1.8 but when I go to mysite.com/forums/resetdismiss.php it says You must be logged in to reset banners. Can anyone help me?
