External Login from 3.0.X to 3.5

[Jako]

I had a login script where users could login from the main site and it would also log them into the forums as well. After I upgraded to vB 3.5 it seems not to be working, any ideas why?

I had something like this and at the top of the page I had

PHP Code:

<?
chdir('forums/');
require('./global.php');
?>

PHP Code:

if(!$bbuserinfo['userid']){
                        print('<b><font color="#D82A2A">Attention:</font></b> You are not logged in, click <a href="login.php">here</a> to login.');
            
            } else {
                        $username=$bbuserinfo['username'];
                        print("Logged in as, <b>$username.</b>");
                    }
