I am new to Python/Django. I have tried over the past few days to install an web application. The installation seems fine, but when I accessed the website, it gave a error :"500 Internal Server Error" and the error.log file is as below.

Do you have any suggestion? Thanks

updated:

After remove lines about CsrfViewMiddlewares as mention by Fedor Gogolev. It gave different error log:

  • This is because the software you are trying to install is not compatible with the version of django (1.4) you are using. Commented Aug 8, 2012 at 19:53
  • it seems like that you are correct, it is not compatible. Any suggestion for this problem? Commented Aug 8, 2012 at 22:25

Try to replace to django.middleware.csrf.CsrfViewMiddleware in your settings file in variable MIDDLEWARE_CLASSES, or just remove if CsrfViewMiddleware already exists, because CsrfResponseMiddleware is deprecated.

He means in settings.py. If you google your error you will find there is a deprecation issue with django 1.3 and 1.4 on this issue.
Probably you have settings.py or some similar file with django settings somewhere in your project directory.
@Fedor: django.middleware.csrf.CsrfViewMiddleware is already there. So I change to django.middleware.csrf ?
No, just remove a string with django.middleware.csrf.CsrfResponseMiddleware.
There is also a line django.middleware.csrf.CsrfResponseMiddleware. Do I need to change anything?
