MarketPress 2.8.9 installed on multisite is not finding mp_productlist template

I have recently installed MarketPress on my multisite to use for a demo subsite. When I was working on the demo as a standalone site the mp_productlist template worked fine, but now it just redirects to the subsite's home page. mp_store, mp_cart, and mp_orderstatus are working fine. Any thoughts? Thank you in advance for your help!
