Hi, we use a secondary site for secure connection. Our site www.skyhighholidays.com send customers to make reservation to www.securepaymentgateway.co.uk. Both site hosted in same server. How can we make it recognised by mozilla as it give a message that www.securepaymentgateway.co.uk uses an invalid security certificate. The certificate is not trusted because no issuer chain was provided. Thanks for your help.
