2kgames Civ 5 wiki error

[Thalassicus]

Is anyone able to log on to wiki.2kgames.com/civ5? I created an account there years ago, but now whenever I attempt to log on, create a new account, or do a password retrieval, I get a session error:

Login error - There seems to be a problem with your login session; this action has been canceled as a precaution against session hijacking. Please hit "back" and reload the page you came from, then try again.
