I have installed marketpress in multisite website. I have done the following settings:
Limit Global Widgets/Shortcodes To Main Blog No
Enable Global shopping cart No
I accordingly used short codes from network page of marketpress for categories and Products.
The products icon /images link properly to their respective blog products.
However, category links direct in the following fashion:
http://main blog website /marketplace/categories/name-of-category/
Please guide us.
