Public Site issue

I have done the upgrade and just discovered my pages are not rederring or bombing on mobile devices.

I am having issues in pulling up the site  http://member.dorothy.com 
On my desktop the site does appear and work.
On my Ipad it stops loading after it fills the screen and I can not scroll down.
On my Iphone it stops loading and if I actually sign in I get “aw, snap”

I an able to get to the page if signed onto Salesforce but not the public site.
