The login procedure works (because the result page showed me that i was logged in as blahbla) .. but now i want to post a thread.. it just doesnt seem to work.. i get a blank result.. When i enter an invalid forum id it returns the invalid forum id message.. but when everything seems right the page returns blank and no post is created. Is there somekind of referer check on newthread.php? Or do i miss something do i miss some kind of variable? Please help me. Is it even possible
