I'm running WPMU 2.7 and I was able to login and edit the sites when they were subdomains of the main install site. However, after making the sites live by connecting them to their domain names, I couldn't login as either admin or as a user. Just in case it was a DNS issue, we've tried using both CNAME records and A records, both with the same result. Right now, if we try and login to either of these sites it kicks us back into the login screen. Even when logged in as admin on the main install site, if we select one of these other two sites it kicks us out into the login screen again.
Any help would be appreciated. We can access the MYSQL tables directly if need be.
Thanks,
Robin.
