Hi Olga,
Thanks for your reply. I managed to figure this out just before I came on the forum – you’re correct, the field is ‘_et_single_layout’. This controls what the product page layout is. I reversed the WP All Import process and used WP All Export to see what custom fields are tagged to the products.
After doing some digging I have realized that the ‘page_product_layout’ field was coming from another theme I had installed prior to prototyping with XStore.
I managed to use WP All Import to doing a mass override on certain products using the ‘_et_single_layout’ and value ‘wide’. It worked.
Anyway we can change the title of this post? It might be misleading for other people seeking info. Can you edit via admin access?
Thanks for your reply.
