My Cron Isn't Posted A Thread!?

[paul41598]

I have a cron setup that runs once per day, that basically moves threads, and after its done it's supposed to post to an existing thread with some log information.

Theres more to the code, but this is the jist of what I'm doing. The move code..and below that, the posting code. The threads move fine..when the cron runs, however the POST IS NEVER made. I cannot figure out for the life of me why it never posts. If I run the cron manually, the move works and the post happens perfectly. Why would manually running it work, but not the actual scheduled cron timer?

PHP Code:

    //Move Thread To Archive Forum
    require_once(DIR . '/includes/functions_databuild.php');
     $threadman =& datamanager_init('Thread', $vbulletin, ERRTYPE_ARRAY, 'threadpost');    
    $threadman->set_existing($getthreadexpire);
    $threadman->set('forumid', $vbulletin->options['threadexpiration_forumarchive']);
    $threadman->save();
    build_forum_counters($getthreadexpire['forumid']);
    build_forum_counters($archive_forum);


        require_once('./includes/class_dm.php'); 
        require_once('./includes/class_dm_threadpost.php'); 

        $postdm = new vB_DataManager_Post($vbulletin, ERRTYPE_STANDARD);
        $postthreadid = '3191';
        $postuserid = '1';
        $threadinfo = fetch_threadinfo($postthreadid);
        $foruminfo = fetch_foruminfo($threadinfo['forumid']);
        $postdm->set_info('forum', $foruminfo);
        $postdm->set_info('thread', $threadinfo);  
        $postdm->set('threadid', $postthreadid);
        $postdm->set('userid', $postuserid);
        $postdm->set('pagetext', "Testing Body");
        $postdm->set('allowsmilie', 1);
        $postdm->set('visible', 1);
        $postdm->set('dateline', TIMENOW);
        $postid = $postdm->save();
        unset($postdm);
