I am getting the same problem as above. I have 2 sites using woocommerce, one of which I haven’t update to the latest version, so I suspect its that the causes the problem.
@nikoza
I’ve tried to follow you solution, but I’m slightly confused about what file you edited etc. I’ve been into the .archive-product.php file in the woocommerce directory but can’t see any reference to the woocommerce_product_subcategories();
Any help would be greatly appreciated as this is driving me mad !!! ;o(
Thanks all
