Moved Forum, cannot log in.

[Gimmick]

Hi

I recently acquired my own private server. and have transfered my site & forum over.

With the forum, I cannot log in since moving. If I reset password or register a new user it is fine.

Any assistance on what I have done wrong?

Thanks

How did you move the site?

Did the URL change, and if so did you update it?
Have you tried resetting the cookie settings.
