django 1.8 cannot load css in development server

Question

I have problem to load css for admin site. I just setup django 1.8 and run development server but apparently it cannot load css with 500 error code. I cannot figure out what is the problem.

This is my setting.py

import os

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

STATIC_URL = '/static/'

this is the error that i get:

This is url.py

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
]

The solution:

The root cause for this is because of the corrupted keys in the Windows Registry. I have reinstalled the python 2.7 library and it solved the problem.

What is the (full) error; please edit your question with the relevant traceback section of the error message. — user707650

Uh, I'm not sure how important that secret key is, but you just posted it to the internet. Might be worth switching to a new one now.... — NightShadeQueen

evrything is a standard code as we use the startproject command — Najmi Hadi

Could this be helpful? The author complains about corrupted keys in Windows Registry. It also provides links to issues in Python's bugtracker: 22028 and 23604 — awesoon

The root cause for this is because of the corrupted keys(have empty string/null value) in the Windows Registry. I have reinstalled the python 2.7 library and it solved the problem.
