问题
I'm not sure how or why this happened, but if anyone could suggest a course of action, I'd really appreciate it. Is there anything I can type into the console to figure out why it's not working? I've tried 'bundle update' a few times and restarted my server, but nothing's working.

So, I found out what was wrong: I had a coffeescript error in one of my XXXXXXX.js.coffee files. I found out this was the problem by reloading the page with chrome's javascript console open. It logged an error and called out the file. I opened the file and fixed the error.
