Unable to access admincp after forum migration
 

Hi there,

I've recently moved a couple of our forums over to a new server, one is working fine the other isn't.

The broken one works fine except I am unable to log in to admincp. My login details are acepted and I get the "Thanks for logging in" screen. Then I am redirected to: Code:
mydomain.com/forums/admincp/?s=asfsdgsdgfsdfasd23432
Which is just the login screen again. Note: simulated random text in qstring as the forum wouldn't accept the actual query string

I am able to log in to the forum proper without issue but again I get the long query string which I guess is a session variable. This didn't happen on the old server.

I was running vbseo but have disabled that in order to log in at all as it was redirecting to the old forum.

In my server errorlog I get repeated entries of:

Code:
File does not exist: /home/mydomain/public_html/404.shtml, referer: http://www.mydomain.com/forums/login.php?do=login
File does not exist: /home/mydomain/public_html/functions, referer: http://www.mydomain.com/forums/login.php?do=login
It's looking for these files in the docroot but the forum is in /forums/
Of course i need access to the admincp to change the forum root.

It doesn't seem to be a cache problem as a fresh install of chrome has the same results.

Any help greatly appreciated.
