One (i hope final) More MarketPress Issue

Urgh, in all the time I've been a member of this site I've never had to ask for support like I have getting this MarketPress feature integrated. I'm hoping it's just labor pains before a magnificent birth, haha!

At any rate.

Aaron's code change fixed my last issue:

Now, I appear to have what looks to be a taxonomy issue?

/shop shows up just fine, and lists "most popular products" and categories without error.

However,

/shop/list/
/shop/status/
/shop/cart/

as well as /marketplace

All return a list of every page I've created on the site, rather than the products that I've listed. Am I right in assuming this is a taxonomy issue? Any ideas on how I could troubleshoot this, or what the problem might be?

I appreciate the patience and support, and look forward to getting this launched to our community!
