Solved Missing Post Content Module - Theme Builder

I know this thread is super old but I just went through this same headache and may have found a solution for others.

Initially I started building a product out using Divi builder and then when I was happy with it I realized I could add the layout through Theme Builder. I was experiencing the popup everyone has referenced, the "Missing Post Content Module" when I was going into edit products.

Every product thats doing this, at least for me, also showed "Divi" to the right of the product in the "All Products" section.

If this is the case for you as well, just go into each of these products and exit the popup when it comes up. Afterwards click the button to "Return to Standard Editor"

The reason being: You do not use the visual builder to edit individual products if you set your theme to All Products
