Hello,
This is how WordPress and WooCommerce work, not a problem with WoodMart or the Pet demo. /product-category/ is only the base part of the URL that sits in front of each category slug, like /product-category/dogs/. It isn’t a real page, so opening it by itself shows a 404 with any theme. Your store doesn’t link to this address anywhere, so visitors normally won’t land on it.
You don’t need to create a page for it. If you want a page that lists all your categories, you can still make it look like the rest of the demo:
– Create a new page and edit it with your page builder.
– Add WoodMart’s Product Categories element. It shows your WooCommerce categories with the theme’s built-in designs. You can also add banners and other theme elements, just like the demo pages.
Best Regards
