I have these following problems any ideas?
1. When they register the confirmation link won't work.

2. When signing in it often doesnt properly redirect

3. When you click keep me signed in and leave the page when you come back, it doesnt always show you still signed in.

1. What is the link that shows up and what should be the actual link?

2. Create a new style with no parent:

Styles & Templates > Style Manager > Add New Style
Parent Style: No Parent Style
Title: Default vBulletin
Allow User Selection: Yes
Save

Then sign in using this totally default vbulletin style - do you still have the same problem?

3. What do you have set for AdminCP > Settings > Options > Cookies > Cookie Domain and do you allow users to login via both www.site.com and just site.com?
