My friends PTR account is only on the cataclysm expasion and theres no way for him upgrade?
It's a bug with some accounts that Blizzard hasn't figured out how to fix yet. Many people, including myself, have this same issue.
Can pull up the PTR but all the realms are red and I can't log on any of them. He'll just have to wait until they come up with a fix to the affected accounts.
