It's really odd though because I have one portal working fine and there all on the same server so it's not an issue with the server environment. I dont think it's related to the subdomain especially because the new accounts are getting updated. It's just that old vbulletin accounts cant login to the portal.

Hmmm thinking of the only thing different between the portal setups and the only thing that comes to mind is that on the first one the admin name for the portal was not the same name as an account on the vbulletin installation. On the second portal however it was originally I did change this though and renamed the admin account to something not in use on the vbulletin installation.

Any ideas? Should I try a complete reinstallation of joomla and the connector? I should have some free time when i am done with school today so I'll give it a try and report back if it fixed the problem.
