How can i solve this problem?

Answer 1

call render_to_response like this:

from django.template import RequestContext

@csrf_protect
def register(request):
    # ...

    return render_to_response(
        'register.html',
        {'form': form}, 
        RequestContext(request)
    )

or just use render shortcut method

@csrf_protect
def register(request):
    # ...
    return render(request, 'register.html', {'form': form})

from 1.8 docs :

render() is the same as a call to render_to_response() with a context_instance argument that forces the use of a RequestContext.
