Question

If i try to open a created url i get an 500 error.

My procedure was:

First python manage.py startapp black

I added in project/settings.py under INSTALLED_APPS 'black',

I added in project/urls.py url(r'^test/', include('black.urls')),

Content of black/urls.py is:

from django.conf.urls import patterns, url
from black import views

urlpatterns = patterns('',
url(r'^$', views.index, name='index')
)

And content of black/views.py:

from django.http import HttpResponse

def index(request):
        return HttpResponse("SHOW ME: BLACK")

After all i synced the database.

I can’t see any error in apache-error-log and also not in my posted django files. What could cause this?

I suggest you to take a look a the several handy ways to log errors with django.
For production, you will want to configure your logging behavior.
You can find an example here in the same docs.

What I personally do in production is enabling email logging, it sends me an email each time there is a fatal error.

Let’s see what it would look like for logging both by mail and in a file:

settings.py

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'mail_admins': {
            'level': 'ERROR',
            'class': 'django.utils.log.AdminEmailHandler'
        },
        'logfile': {
            'class': 'logging.handlers.WatchedFileHandler',
            'filename': '/var/log/django/your_application.log'
        },
    },
    'loggers': {
        'django.request': {
            'handlers': ['mail_admins'],
            'level': 'ERROR',
            'propagate': True,
        },
        'django': {
            'handlers': ['logfile'],
            'level': 'ERROR',
            'propagate': False,
        },
    }
}
