I’d tried reloading a few times already, to no avail.
So the browser I normally use is Chromium (currently v. 52.0.2743.116 (64))
Konqueror is told it’s not supported
I’ve tried loading the exercise in Firefox (48.0.2-1) and also didn’t work.
Running all these under Arch Linux. I’ve completed the entire Ruby course under this setup and the Rails course up until this exercise. Don’t think it’s an update thing either cause I’d been working for quite a while in the day this problem showed up. If it was I’d expect the issue to have manifested when I first began working
I’ve seen a bunch of reports of people being failed on exercises for no apparent reason in the Rails course this past day or two, so I think it’s a bug on Codecademy’s end. My best suggestion is for you to file a bug report with them, then wait a few days and come back to the course
