I know this is an old thread, but I'm having a similar problem. My vbulletin forum is installed on domain.com/forum but I wish to extend the session over the entire website. I extended it on the main domain (domain.com) by using a global $vbulletin and everything works fine. However, I have a number of sub directories with mini sites , each of them a wordpress install and I can't make it work the session sharing. I also use the global $vbulletin on domain.com/site1 or domain.com/site2 and I cannot see the user when logged in. Any idea how I can do it without requiering global.php? Is is a cookie matter? 10x.
