#27 Bug while login on linux

I tried server on hashbang and raised error when I try to login:

500 Internal Server Error

The server encountered an unexpected condition which prevented it from fulfilling the request.

Traceback (most recent call last):

Does the Ubuntu mono font exist on the working directory and is it readable for our server app(permissions)?

oh late reply!

How about disabling captcha until we create our captcha server related to issue 2?

Did you check what I said?

Ok I confirm that this bug exists.
