Access-Control-Allow-Origin error

Hi;

We use multi-store nopcommerce (two .com and one .co.uk site).
We getting Access-Control-Allow-Origin error your trial Nop One Page Checkout plugin on only .co.uk site.

The full error message that i seen chrome console "Failed to load https://www.mysite.co.uk/RealOnePageCheckout/GetCheckoutData:
Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://mysite.co.uk' is therefore not allowed access."

We try different browsers and computers but the problem continue.

Could you please help us?
