Can't purchase the software online (CORS issue)


It’s likely not the best place to put that question, but I did not find a better place.

I am trying to purchase the software online, and I get issues on Chrome. Apparently, this is related to CORS protection:

account/:1 Access to fetch at '' from origin '' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

After this, the window to buy SignalRGB simply disappears.

Any solution?
