John Lewis website pages don't load

i'm having problems with the John Lewis website. Only the first page of any search will load. When I click on the next page I just get a blank white screen. this is using my IPad 2. It's only just started happening after many years of use and accessing this site. Other sites are also showing similar problems Ie not all items on page load. Is this my IPad or the website? I have kept up to date with all bug fixes and upgrades. Anybody else had this or similar probs , I'd be very grateful to hear your thoughts.
