Featured Slider and featured image not appearing on iphone

I'm hosted by Godaddy. blog.mrhoni-photography.com Adventurous Pro v 3.0. I have not updated because I never made a child theme and not fond to have to start over. My blog is OK on my desktop imac. When I look at the blog home page on my iphone, the featured slider is not displayed and the featured image for each post is not displayed. Its been awhile since I looked at my blog on an iphone but I thought those two features used to be there.
