Click to re-edit doesn't allow us to re-edit the product

Hi,

When clicking to re-edit or clicking the url connect to the thumbnail of the product it takes us to a blank page. Do you know why this may be?

We are using wordpress and the OceanWP theme. 

Here is the link generated: https://www.paintwise.ai/product/square-card/?cart_item_key=d31edbe63baa89ffac3840e84a91543e

Here is the store so you can recreate yourself: https://www.paintwise.ai/product/text-to-image-card/#Home

Many Thanks

Seamus
