The newest version (release September 9th 2013) of the UserReport script supports both regular HTTP pages as well as HTTPS and SSL. This means that you can use the default script no matter what kind of website you have.
Previously you had to obtain an altered version of the UserReport script if you wanted to run our services on HTTPS or SSL pages. The altered scripts are still supported, but you may also exchange it with the new script which is now available at your account. You find the new script by going to "settings" --> "website details".
