product shows in global product widget but hyperlink returns 404 error

Marketpress Version 2.4.2
gridmarket 1.4.8

I have domain.com with product theme
domain.com/site2 with grid market theme
domain.com/site3 with grid market theme
domain.com/site4 with grid market theme

On domain.com/site2 I am trying to list all of the global marketpress products.
I use the global category widget to list products in the sidebar.
When I click on an item that was published on site3 and that is listed on the global category widget on site2 it takes me to domain.com and says page not found error. I would at least expect the error to show on the domain/site3 if their was an access issue.

In network settings>sites> I have domain.com/site2 as the main site.

What am I doing wrong?
