I am using WC 2.0.9, and a structure like this:
- Category
-- XX Products
-- XX Subcategories
--- XX Products
--- XX Subcategories
---- XX Products
I have set category view mode to "both", because a category can contain both products and subcategories.
When showing the top category archive I get a listing of subcategories, and all products, including those attached to the subcategories. Is there any way to avoid this?
