Hey Stephen, thanks for taking a look. Yeah, after a few hours spent trying to hack a solution together, I gave in and went with the 2014 theme for the time being. I would really like to get the montezuma theme going though if I could.
Thanks Stephen! Turns out it was actually my theme (and probably threaded replies). After turning off all the plugins, I finally switched the theme from “Responsive” to twetytwelve and lo and behold: it worked again.
