There is a problem in your bb-config.php, most probably in the first line.

Normally, HTTP-requesting bb-config.php should not create any output. But try

and see the strange “”. I cannot get, what the problem exactly is, but it is the bbPress configuration file for sure. After login, bbPress tries to set a cookie. This is done by sending an HTTP header. But if there is any output before the PHP header () invocation, PHP sends a generic header, which lets the cookie fail. Result: you can not login.

Ich hoffe, es hilft ein bisschen — und sorry für mein mieses Englisch

Oh, ich vergaß — Oh, I forgot

If you want a german language file for bbPress 1.0.2 (with the formal “Sie”), take my translation — Wenn du eine deutsche Sprachdatei für bbPress 1.0.2 haben möchtest, nimm meine Übersetzung.
