Public Page is broken

Hi,
I was adding my first items but when I wanted to see how it looked in Public Page I got this error message. The only thing that was changed was the fileDerivatives.strategy that we changed from External_ImageMagick to Imagick. Has anyone had this problem before ? Thanks !

This error shouldn’t have anything to do with your choice of derivative strategy: it’s complaining that the theme is trying to load a file (css/slick.css) that doesn’t exist.

The error seems to be coming from the Connected Carousel plugin.

I deleted the Connected Carousel plugin, and everything is working once again, thanks a lot !
