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:

• Your browser is accepting cookies.
• 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.

Thanks,

CSFR stands for Cross-Site Request Forgery: see https://en.wikipedia.org/wiki/Cross-site_request_forgery. In order to prevent this kind of vulnerability, forms pass around special CSRF verification tokens, to validate POST requests as authentic. The error you’re seeing indicates that the page didn’t pass the necessary CSRF verification token when trying to log in, and so the web server blocked the login attempt.

I’ve seen this error before when there was a problem compiling coffeescript. Can you verify that that’s working properly?

Hello,

Solve this problem, as two jQuery was loading inside the code. 

Second jQuery erased jQuery.cookie object.

You could change the cache.py file into the path directory:  /edx/app/edxapp/edx-platform/common/djangoapps/utils/cache.py

The only thing that you must do is to change the def wrapper funvction adding the command "return view_func(request, *args, **kwargs)" as below. Using that command you don't cache the pages so the crfs tokens can be changed.

    def decorator(view_func):

        """The outer wrapper, used to allow the decorator to take optional arguments."""

        @wraps(view_func)

        def wrapper(request, *args, **kwargs):

            return view_func(request, *args, **kwargs)

            """The inner wrapper, which wraps the view function."""

            # Certificate authentication uses anonymous pages,
