[punterzone]

Would someone be able to tell me what I'm doing wrong here?

PHP Code:

define('START_CWD','/home/pzone/public_html');
define('CWD','/home/pzone/public_html/forum');
chdir(CWD);
include_once CWD.'/includes/class_hook.php';
include_once CWD.'/global.php';
chdir(START_CWD);
include_once('/home/pzone/public_html/forum/includes/functions_login.php');
$password=$_POST['password'];
$username=mysql_real_escape_string($_POST['username']);
$results=mysql_query("SELECT userid,zip,password,salt,dispid FROM com_user WHERE username='$username' LIMIT 1");
$row=mysql_fetch_assoc($results);
$password=md5(md5($password).$row['salt']);
$md5_pass=md5($_POST['password']);
$check=verify_authentication($_POST['username'], '', $md5_pass, $md5_pass, '0', '1');
if($check){
    exec_unstrike_user($username);
    process_new_login('', $username, '');
    $vbulletin->url='/index.php';
    $cookie_salt="kba1j5MmRINZnEnhOEtWrptt0V1ej";
    $cookie_password_salted=md5($pass.$cookie_salt);
    $useragent=$_SERVER['HTTP_USER_AGENT'];
    $userip=$_SERVER['REMOTE_ADDR'];
    $vbidhash=md5($_SERVER['HTTP_USER_AGENT'].$userip);
    $vbsessionhash=md5(uniqid(microtime(), true));
    $session_time=time();
    $cookie_expire=31536000;
    $site_domain="punterzone.com.au";
    $url_path="/forum";
    mysql_query("DELETE FROM session WHERE userid=1 OR host='$userip'");
    mysql_query("INSERT INTO session VALUES ('$vbsessionhash', '1', '$userip', '$vbidhash', '$session_time', '/forum/', '$useragent', '0', '0', '2', '0', '0', '0', '0', '0', '0','','')");
    setcookie('bb_lastvisit',$session_time,$cookie_expire,$url_path.'/',$site_domain); 
    setcookie('bb_lastactivity',0,$cookie_expire,$url_path.'/',$site_domain); 
setcookie('bb_sessionhash',$vbsessionhash,$cookie_expire,$url_path.'/',$site_domain); 
    setcookie('bb_userid',$userID,$cookie_expire,$url_path.'/',$site_domain); 
setcookie('bb_password',$cookie_password_salted,$cookie_expire,$url_path.'/',$site_domain); 
    exec_shut_down();
    header('Location:/');
    exit;
}else{
    header('Location:/loginfail');
} 


Logs in fine on my external site, but the user (userid=1) is not logged in when I load the forum

--------------- Added [DATE]1314731113[/DATE] at [TIME]1314731113[/TIME] ---------------

Just noticed I'd set cookie_expire to the past, but I've sorted that and still it does't work.
