Login not persistant
 

I am moving my forum to a new server.
Successfully moved the database and the software.
The domain name still points to the current server.
I am testing everything before switching the domain name over to the new server.

Problem: When I try to logon to the new server, it accepts the user and password as valid but returns to the forum as not logged in... both in the regular forum and in the admin control panel.

It must be a cookie issue. Is there something I need to do to make this work temporarily or what did I forget?
