Ok I tried without a function and purely tried on the else statement:

PHP Code:

            if (isset($_GET['submit'])) {
                if (empty($_GET["username"]) || empty($_GET["when"]) || empty($_GET["where"]) || empty($_GET["offence"])) {
                    $formErr = "<br>You have not completed the entire form - everything must be completed! (*)";
                } else {
                    $username = $_GET["username"];
                    $when = $_GET["when"];
                    $where = $_GET["where"];
                    $forumid = "33";
                    $threadinfo = array();
                    $foruminfo = fetch_foruminfo($forumid);
                    $threaddm =& datamanager_init('Thread_FirstPost', $vbulletin, ERRTYPE_ARRAY, 'threadpost');
                    $threaddm->set('forumid', $forumid);
                    $threaddm->set('userid', "1");
                    $threaddm->set('pagetext', 'textul meu');
                    $threaddm->set('title', 'titlul meu');
                    $threaddm->set('allowsmilie', '1');
                    $threaddm->set('visible', '1');
                    $threaddm->set_info('forum', $foruminfo);
                    $threadid = $threaddm->save();
                    build_forum_counters($forumid);                    
                }
            } 


And still receiving a blank page (assuming error).
