Reply To: All my category page turns into blank page first and now is 404 page

We are glad that you sorted it out. The problem was caused by an empty custom layout created in Dashboard -> WoodMart -> Layouts. We disabled it and now it works correctly. If you want to use our custom layouts you need to fill it with shop page elements. Read more information in our documentation https://xtemos.com/docs-topic/shop-page-builder/

Let me know if the issue is solved or you have any extra questions I can help you with.
