iframe

I have a couple of questions regarding this unauthorized access page. The error on this page is saying "your session may have expired". When accessing the designer in our iframe in Safari, we are seeing this eSignLive unauthorized access page. Is this a bug? We do not see this page when accessing the same link in any other browser. Please advise. Can the unauthorized access page be white labeled? We are showing this in an iframe in our application and would prefer if these error messages do not say eSignLive or have your support information on them. Thank you Colleen
