I am receiving this message when trying to download on one of my websites.

Unauthorized access to Downloads.
Error! Either you tried to start downloading from an unauthorised resource or your browser did not send a referrer.

When I login to another one of my websites which has the same setting for options I don't get this error.

Thank you
