Slider problems

Hi,
On this page: https://moccasin.se
the slider suddenly disapeard

I’ve tried everything, but don’t manage to get it back.
The start page is set to Home page, and I added new pics but they don’t appear?

How shold one perform to get the pics into sliders on home page?
I have uploaded then from computer, added into page, and, in order not to see them embedded on page, I delete them from there.
Then I hav got the slider work, but not now?

What could be wrong?
