eCommerce isn't working

ecommerce isn’t working on one of the sites I manage. I feel like it is a bug with Webflow, as nothing changed between it working and then not working, but would appreciate some guidance, please.

If you go to the link below and click on any of the collections and try to add any product to cart (available or sold), you get an error. Also, if you open the cart, the cart counter doesn’t appear and there is an error in the bottom of the cart panel.

Hi @Matteo_Grand,

Have you reached out to customer support. This looks like a bug that needs to go through them first.

Thank you - I’ve just reached out
