Slider and highlight images not working anymore

Hello,

I looks like the update created a problem on my site.

I didn’t changed any settings (since everything was working fine) but now I can’t set the slider neither the latest articles images anymore.

What is weird about that is that I see all the infos and links in the tempera settings.

I can even see the images of the sliders when I’m following the links.

Like I said before everything was perfect and I didn’t changed anything (no plugin either) but since the theme have been upgraded to the latest version nothing is working anymore.

Any clue?

Thanks
