Hmmm....sounds like maybe customers could have used a fair warning about not upgrading their phpbb forums....
Anyway...I managed to restore the header part by changing the code to call it from the old forum front end that I saved.
See it here: www.naturemoms.com/reviews
So how can I make the rest of the template from the old forum show up...it seems like there must be a way to do this.
Worst case scenario is it possible to purchase another installation and have it re-done?
