Timemapper HTTPS issues

I have a Joomla site that uses https by defuault.
When I add my timemap in an iframe, it will not display as the javascripts used are http.
Is it possible to change this?
This is a great library, I do hope it continues. I notice that Rufus Pollock has not answered question since 2015. Is this still being monitored/developed?

I faced the problem recently in Google Sites. I could not load TimeMapper. But then I set web address as my .net domain. Now it’s ok because every domain linked to Google Sites uses http by default. :slight_smile:
