sclogin 8.0 - modal popup not working anymore

Hello,
I tested the upgrade to V8 both for JFBC connect and the SClogin module.
The SGlogin modal popup is not working anymore (test here accademiainfinita.it/test/ - top right of the screen)
On my live site I still have V7.2.5 and is working fine, every setting should be the same as the test site so it's probably the new version?

I also have jQuery Easy plugin installed, but it's not helping in this case.

Well... as soon as I finished posting this, the modal popup began working normally, maybe was a browser cache issue...
