Access denied. after post save

[kamilkurczak]

Hello,
I wrote my own system to save post on outside forum page (using data manager). Post is saved correctly but after save I have a blank page with : "Access denied." message.

example of my code:

PHP Code:

global $vbulletin;
        require_once(CWD . '/includes/init.php');
        require_once(CWD . '/includes/functions_misc.php');
        require_once(CWD . '/includes/functions_databuild.php');
        
        $foruminfo = fetch_foruminfo($forum_id);
        $threadinfo = fetch_threadinfo($thread_id);
        
        $postdm =& datamanager_init('Post', $vbulletin, ERRTYPE_ARRAY, 'threadpost');
        //$postdm = new vB_DataManager_Post($vbulletin, ERRTYPE_STANDARD); 
        
        // set options
        //$postdm->setr('showsignature', $post_data['signature']);
        $postdm->setr('allowsmilie', $post_data['enablesmilies']);
        //$postdm->setr('htmlstate', $post['htmlstate']);
    
        // set data
        $postdm->setr('userid', $post_data['userid']);
        $postdm->setr('threadid', $post_data['threadid']);
        $postdm->setr('parentid', $post_data['parentid']);
        //$postdm->set('username', $post_data['username']);
        $postdm->setr('title', $post_data['title']);
        $postdm->setr('pagetext', $post_data['pagetext']);
        $postdm->setr('iconid', $post_data['iconid']);
        $postdm->setr('visible', $post_data['visible']);
        $postdm->setr('dateline', time());    
        $postdm->set_info('forum', $foruminfo);
        $postdm->set_info('thread', $threadinfo);    
        $postdm->pre_save();
            
        if(!empty($postdm->errors))
        {
            return $postdm->errors;
        }
        else
        {
            
            $post_id = $postdm->save();
            
            build_thread_counters($threadinfo);
            build_forum_counters($foruminfo);
            
            return $thread_id;
        } 


can you help me? Thanks
