Wow. A "responsive" page that hates all but a couple specific aspect ratios. It literally won't show you the page if you aren't in an aspect ratio it expects. WTF? http://d.pr/i/12ZBj
I had a similar issue, tfw "responsive" means adapting to the site rules, not the other way around. Reminds me of "This site is best viewed in 1024x768", just poor web dev work.
