Slider snippets not working on new version

Hello everybody,
I’m writing here because I noticed that with the (free) version 3.5.5 of the theme the Snippets I used for the slider aren’t working anymore on the website I maintain. (www.sismed-it.com)
I’m particularly interested in the fader snippet, which was working fine on previous versions.
I tried add the code on the style.css of my child theme, I tried add it on the CSS options via customise page, but none of the options seem to work out.
For the sake of completeness I tried to deactivate every single plugin I’ve been using on but nothing seems to work out.

Every help will be highly appreciated!!

Cheers,
