My home page is not responsive on mobile device; the slideshow banner does not appear nor can I click on the menu. 

However, the other pages, seem to appear just fine, even when I switch from desktop to mobile view, it works with no problem, but the home page, the first page everyone will see when they visit, doesn't show the slideshow banner and doesn't allow for users to click on the menu. I watched a video tutorial on how to add a slideshow full screen banner, which works fine on web, but again, on mobile, it disappears. 

Please help.
