Frontpage Slideshow – no previsualisation

I’ve some issues with the previsualisation in the admin section. Nothing appear. I’ve tried to shut down every other pluggins and still nothing.

I’ve tried to put the shortcode on my frontpage and nothing neither appear on the site. I’ve tried to link directly to the front page and… nothing.

I have this pluggin on an other website and it works really fine… (great pluggin by the way!)

I’ve seen differents discussions about this, but apparently this was fixed by a new release… so can anyone help me?

Thanks
