Django 1.6.5 STATIC_URL in templates

Question

I really need your help. I know that this question has been asked many times, but now I'm faced with strange behavior of django 1.6.5. The problem is that in my project stopped working STATIC_URL's in templates. My settings:

STATIC_URL = '/static/'

STATICFILES_DIRS = (
    os.path.join(BASE_DIR, 'static'),
)

• BASE_DIR = os.path.dirname(os.path.dirname(file))

Other settings are set to default.

{{ STATIC_URL }} in template returns empty sting.

I try to use STATICFILES_FINDERS, TEMPLATE_CONTEXT_PROCESSORS in settings - nothing has changed.

Attempts to changes in views.py:

def home(request):
    return render_to_response('index.html', {},
                              context_instance=RequestContext(request))



@render_to('index.html')
def home(request):
    return {}
