UBB.threads PHP Forum Software Community Forums UBB.threads 7 Installation and Upgrade Support Can't log in after upgrade...

I filled out a support ticket on this as well, but thought I would post here to see if someone on this board could help quicker.

I just upgraded to the latest version 7.5.4.2 and the upgrade appeared to complete successfully, however, now no one can log in...including myself as Admin. I have tried clearing browser caches, checked permissions on the folders, double checked the sql database info and have cleared all the files from the sessions folder. None of these have solved the problem.
Anyone have other suggestions I should try?
Thanks in advance for your thoughts!

Forgot to add that the message I receive is just "Access Denied" when trying to log in. From what I can tell the settings are correctly pointing to the database in the config file.
