I'm using WP e-commerce 188.8.131.52
I have a lot of products on a website, so have to be careful with what I do so not to delete them all...
Basically we just migrated a load of products from one system to WordPress. There's lots of categories, with a menu which displays how many products are in each category.
It was working fine and displaying the products, then all of a sudden when you click on a category it says 'There are no products in this group.'
The products are displaying on the full product listing, just not for each category..
