Featured content: slider disappeared

Hello Zulf !

Thanks again for the incredible speed of your answers and the time you give to help Ridizain users, it’s pretty amazing.

I have an issue with the Featured Content slider : since I updated Ridizain, the slider has disappeared on the front page and on the settings screen, whereas the grid still works if I tick it. I use Featured Content with posts tagged “featured” as usual but the slider just do not appear at all, whatever setting I choose.
Here is the website if needed : http://uvsq-post.com/

Is a setting wrong or something ?

Thanks again for helping users of your very handy and well-conceived theme !
