It was the admin application, which should be using HTTPS when you access it over HTTPS right? I just tried with a test app and the same thing happens.
I commented out like 518 in rocket.py and that silences the errors, but is that a good thing? There might be another problem here. I just checked the traffic going to my test app and all requested files (including the static ones) are requested over HTTPS, however, Google Chrome has disabled my JavaScript because "This page has insecure content". All the static files are loaded locally (I'm not using a CDN or anything). So are the files getting returned to the browser over HTTP instead of HTTPS or something and that's why the rocket error was happening?
