Hello,
I’ve an issue with “Add to cart” button in product page. When I click on it I get this message “Required parameter missing or invalid: items”
Weird thing is that it happens just on single product page and not in collection for example
Product page https://longsongbooks.com/collections/antichita/products/memoires-de-j-casanova-de-seingalt-ecrits-par-lui-meme-suivis-de-fragments-des-memoires-du-prince-de-ligne
Collection page https://longsongbooks.com/collections/all
I didn’t touch the code and I have just Facebook app installed, so I don’t get what the problem could be.
Can you help me with it?
Thank you
