hmm, i still get stuck with this. Now i get the following if i try to "login as an other person": The action 'FacebookLoginForm' does not exist in class Security
in error_log.txt it says:
[15-Oct-2010 02:43:33] Warning at sapphire/core/control/Controller.php line 464: Already directed to https://www.facebook.com/logout.php?api_key=147460175293223&next=http%3A%2F%2Fwww.flavourtripping.de%2FSecurity%2FLoginForm&session_key=2.dHGQbJw2au28pcpjg9GBUQ__.3600.1287151200-1513896489; now trying to direct to http://www.flavourtripping.de/Security/Login (http://www.flavourtripping.de/Security/LoginForm)
There must be a loop that has to be exit or must die. But i can not find where?
@willr: does facebook-connect work aot of the box for you?
