OAuthException : Eine active access token muss verwendet werden, zur Abfrage von Informationen über den aktuellen Benutzer

Ich versuche, führen Sie die Beispiel-code für Facebook-connect, die ich heruntergeladen http://thinkdiff.net/facebook/php-sdk-3-0-graph-api-base-facebook-connect-tutorial/

Ich bekomme diese Fehlermeldung :

[error] => Array
            (
                [message] => An active access token must be used to query information about the current user.
                [type] => OAuthException
                [code] => 2500
            )

Können Sie versuchen, Sie auf meiner website : http://facebook.oliverjordan.net/thinkdiff

Hier ist die fbmain.php code :
