Clean Education (free) bad display only on ihone

My site http://walnutcreekband.org doesn't display properly on an iphone (at least on my 5S). On the phone it always gives 404 (only on the initial access - if I press Home it loses the 404) and it displays things I don't have setup, like Search and Archives and doesn't display things I do have setup like Featured Content (3 columns). Very strange and annoying. Any help appreciated!
