CSRF token missing or incorrect on one page

Question

Have a homepage there every page with a form works fine.
Added a form to my start page and in my local server it works fine.
But when I add it to the production server it does not work.
It say's that CSRF- token is missing or incorret.
But I have added the token, and it works all the other pages.

What is that I'm missing... ?

View

  @login_required
    def start(request) :
        libs = Library.objects.all();
        header = Header('Start');
        studies = None;
        source = None;
        if request.method == 'POST' :
            if 'Show_studie' in request.POST:
                studies = Study.objects.all;
            if 'Show_source' in request.POST:
                source = Source.objects.all;
        dctArgs = {
            'library_list': libs,
            'styles_dir': conf.styles_path,
            'header': header.html,
            'studies_list':studies,
            'source_list':source,
            'images_dir': conf.images_path,
            };
        return render_to_response('start.html', dctArgs, RequestContext(request));

Forbidden (403) CSRF verification failed. Request aborted. Help Reason given for failure: CSRF token missing or incorrect.

In general, this can occur when there is a genuine Cross Site Request Forgery, or when Django's
CSRF mechanism has not been used correctly. For POST forms, you need to ensure:
• The view function uses RequestContext for the template, instead of Context.
• In the template, there is a {% csrf_token %} template tag inside each POST form that targets an internal URL.
• If you are not using CsrfViewMiddleware, then you must use csrf_protect on any views
that use the csrf_token template tag, as well as those that accept the POST data. You're seeing the help section of this page because you have DEBUG = True in your Django settings file. Change that to False, and only the initial error message will be displayed.
You can customize this page using the CSRF_FAILURE_VIEW setting.

Settings

MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
)

On the page that working I get this message:

<django.contrib.messages.storage.fallback.FallbackStorage object at 0x03B7A270>

We cannot help you unless we see the code that you are using. So update the question with your views.py and your template that is causing the problem. — Burhan Khalid
CRSF token works with cookies and HTTP headers. Did you change of web browser ? Can we have some information about your server & browser cookie policies, and about how you added the CSRF token ? — Ricola3D
Ah, here it is: return render_to_response('start.html', dctArgs, RequestContext(request)); should be return render_to_response('start.html', dctArgs, context_instance=RequestContext(request)); — Henrik Andersson

Try wrapping your view in the @requires_csrf_token decorator, like so:

from django.views.decorators.csrf import requires_csrf_token

@requires_csrf_token
@login_required
def start(request):
    ...
