Session verification failed. Please try logging out and back in again, and then try again.

I've cleared the forum cache, checked for errors, changed the cookie name, and disable caching, but no change.

Nothing has changed on the cPanel server except for the nameserver, it used to use BIND and now it uses PowerDNS.
Do you think this has anything to do with it?
