Facebook SDK not loading

Hello.

I try now for a couple of days to get the Facebook SDK for Unity to work. I have the Interactive Console Demo what comes with the package on an HTTPS Server and aim on it within my app on facebook.

In the Editor the Demo works, but in the browser not. It just say "Facebook DLL: Not loaded"

I searched alot and tries many things (also uploaded it to an other server) but nothing help me.

Has someone an idea?
