Don't know if this is a quirk with my board or not.. but something you might want to check. Each time I go into edit my Config settings, it defaults post tracking to "off". I have to choose "full post tracking" from the pull down each time I go in there to change something.
Might want to check that if it seems the post tracking is off since you reinstalled the original template. If yours is doing what mine is, and you went in to change something, it might be off.
