E-commerce Error during checkout

Hey there, nothing happens when I click on the checkout button and I cant figure out why.

Used to work fine and I don’t know what happened. All my products are free and do not require shipping, I do ask for the shipping information from my clients though because I want to contact them regarding their enquiry.

I did change one product to “requires shipping” and then it worked again, but only once. Changed the product to doesn’t require shipping, it worked again but only once. Could be a coincidence – but I am lost. Please help!

Cheers, Kati
