Error: Invalid product:
1- Is your customization page defined as homepage
2- Is your customization page defined as one of woocommerce pages
3- Does the product you are trying to customize exists and is published in your shop
4- Are you accessing this page from one of the product designer buttons
You need to add a widget, row, or prebuilt layout before you’ll see anything here. 🙂
Looks like you're trying to access the configuration page directly. This page can only be accessed by clicking on Build your own button from the product or the shop page.
