I just realized your doing that a bit different then I do when it comes to inisializing the datamanager. I believe your are doing that wrong. You are accessing the threadpost class directly which might be why you are not geting post count updates.

Use this instead.

PHP Code:

$threaddm =& datamanager_init('Thread_FirstPost', $vbulletin, ERRTYPE_ARRAY, 'threadpost'); 


Also, when starting a new thread you should not be passing the forum id, you shoud be passing the foruminfo array.

PHP Code:

$forumid = 2; //Or however you are ariving at that.
$foruminfo = fetch_foruminfo($forumid); 


And then in your datamanager instance use setinfo not set, as follows.

PHP Code:

$threaddm->set_info('forum', $foruminfo);
$threaddm->set_info('thread', $threadinfo);
