Runtime Error on the Demo

[sgatibaru]

I wanted to try out the app before installing and reconfiguring my server (its a production server). I got the error:
Runtime error

Space failed. Exit code: 1. Reason: Traceback (most recent call last):

I guess nothing has changed since August last year. Still same error.
