Having issues with WPMUDEV themes and MarketPress now as well

http://s17661.p20.sites.pressdns.com/store/products/realis-vibration-g-fix-68-by-duo/

theme is spirit

We cannot get a product page to behave correctly or look good.

We put in a test product with 2 versions....only one photo show up....huge photo and none of the image settings work. Also, there is no add to cart button or really any other prompts that you would expect an ecommerce site to have.

Where can we get support docs for MarketPress?
