No products showing up on product-category pages

Hello,

When I click on a category I get this message “No products found which match your selection”, and the heading of the page is always “Archives for:….” whatever the category name is.
See example here: https://aftradvillage.com/2013/shop/product-category/paintings

But on the shop page all the products are visible.
https://aftradvillage.com/2013/shop

I created pages myself and inserted the shortcode to display the products for each category. e.g. https://aftradvillage.com/2013/shop/african-print-gallery

Anybody know why the category pages don’t work?
Thanks for any help!
