I have a friend in Germany who was not able to register for my xenforo site for some reason (registration kept kicking him back when he clicked Finish), so I registered him manually. Now, however, he tried to log in and tells me this happens: First he said: This time, when I tried to log in, I received the message "Cookies are required to log in to this site. You will not be able to login until they are accepted." As I allow cookies, I really have no clue what the problem is, but I'm close to giving up. Then he said: I played around with my anti-spam software and browser cookie settings, so it should really work now, but still...when I try to log in, I get the message "This action is available via POST only. Please press the back button and try again." Any ideas? Thanks.
