WooCommerce return 404 on category pages

I am trying to set up WooCommerce permalinks to get something like:

• example.com/shop/ => Shop page listing products
• example.com/shop/category-name/ => Category page listing products from a category
• example.com/shop/category-name/product-name/ => Product page showing product details

But I have a 404 not found error when trying to open the category page.

What I did is:

• I created a “Shop” page and I set it as the shop page in WooCommerce settings. OK: The page works fine and is displaying all products.

• In WordPress permalinks settings, I set the product category base to “shop”. KO: When I try to display a category page, WP returns a 404 error (but links are properly generated in the shop page sidebar and 404 error occurs while clicking on them).

• In WordPress permalinks settings, I set the product permalink to “/shop/%product_cat%”. OK: Products pages are displaying without issue.

Any way to solve this?

Under Custom Base where you have used /shop/%product_cat% needs to be replaced with /shop/%product-category% Please see screenshot below:
