sheduler doesn't work over ssl

The extension is perfect and works excellent for me.
My only problem is that i’d like my site to run over ssl but because of this extension i can’t!
It’s not even loading ,it shows empty.
Also at the back end i have the same problem. I need to manually change the url to http every time i have to check sheduler.

Is there any solution to that? something i can do to make ti work?
Thanks you very much for your help and your excellent work!
