The checkout-wizard does not continue when I click “next to payment”.
In my console I got this CORS error:
Access to XMLHttpRequest at ‘https://app.snipcart.com/api/cart/xxx’ from origin ‘https://xx.xx.xx’ has been blocked by CORS policy: Method PATCH is not allowed by Access-Control-Allow-Methods in preflight response.
Note: My website is in Test-Mode and reachable under a subdomain.
Note 2: I have one product and this has the same data-item-url (with https) as configured in the domain section of the control panel.
