Prevent Creator using https

Prevent Creator using https

Hi

My app has been working for fine for years at the following URL

https://creator.zoho.com/rsoftley/ast/view-perma/FINAL/

but now I've discovered Firefox and IE are causing massive problems with secure pages that mix secure and insecure content.

Whenever I go to  http://creator.zoho.com/rsoftley/ast/view-perma/FINAL/ it redirects to the https version - is there any way to stop that from happening or another way to fix my problem?

Thanks

Robert
