Lynne, I think you nailed it.

We have AME which parses URL from videos services into display windows.

Here is one plugin which has UPDATE attributes and it directly affects pagetext field from the post table

Hook Location is newpost_complete

require_once(DIR . '/includes/ame_bbcode.php');
$value = ame_prep_text($post['message']);
        if ($value == 1)
        {
                $vbulletin->db->query_write("UPDATE " . TABLE_PREFIX . "post SET pagetext ='" . $vbulletin->db->escape_string($post['message']) . "', ame_flag=1 WHERE postid=$post[postid]");
        }
        else if ($value == 2)
        {
                $vbulletin->db->query_write("UPDATE " . TABLE_PREFIX . "post SET ame_flag=2 WHERE postid=$post[postid]");
        }

I will try to identify if this is the real cause. I will surely report back, so others don't have these kinds of headaches.

Regards,
Val.
