Slideshow dissapears when logged

I am creating a website, and I always used slideshow ck for my websites.
But, for some reason, in this website, when i log to the site as administrator, the slideshow is gone.
I've used the inspector and the slideshow div is still there, just not visible.
What could this be?

Update: Just discovered that this happens only on the main page.
