eCommerce Plug-in not working with my theme...

Installed... the plugin works fine all the way through checkout when activated on theme twenty14.. that is great!

However, on my WP theme Gonzo, the cart, products and checkout page, etc will not display. If I add the cart to the sidebar, it will show items in cart, however, I am still not able to check out.

Please take a look and let me know what you think is in error.
