Every time I log in I get:
vBulletin Error
Invalid Redirect URL (http://www.eaaforums.org/)
rather than the "click here if you're not redirected" screen. It seems to inhibit the "remember me" cookie as well.
By the way, are we ever going to get off vB4? Lots of security issues and they don't support this version anymore. (We moved up to XenForo 2 which has better support) on my sites.
