I'm logged in in Facebook, but i am not logged in in Xenforo.
If i log me in in Xenforo on this Site http://xenforo.com/community/login/
I get this error :
Error: Error Redirection The site is redirecting the request in a way that they will never complete. This issue can sometimes occur when cookies disabled or rejected are.
If i log me in by the Bar it work
