One page not displaying correctly on tablet

Hi there, 

I'm working on a site for someone and all my content is displaying correctly, in that it is converting to phone/tablet display when i look at it on my ipad, except for one page. This particular page is displaying like it is being viewed on a desktop computer. Is there a setting somewhere that I may have accidentally selected and if not has anyone else come across this issue and have any tips to fix it? 

Thanks in advance.
