CSRF token missing or incorrect

[chfism]

I always meet the problem when do ops. It happened occasionally and can be fixed by refreshing the page, but it's really annoying, especially when the network is slow.

Here's the whole error msg
======================================================
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.

==============================================

Aslo I've google it and find a possible solution

You need to add 'django.middleware.csrf.CsrfResponseMiddleware' in your setting.py file, it looks like that:


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',

'django.middleware.csrf.CsrfResponseMiddleware',

)

do you have multiple tabs open?

[chfism]

yes. I think so. Does that mean we can't open utopia in multiple tabs?

[Landro]

I often have 8+ Utopia tabs open in FF and never had this problem.

[Decibel]

Same here, using Mozilla and when I'm not in war I always have multiple tabs open without problems.

Multiple tabs can sometimes (not always obviously) cause funny issues with security features as they basically mimic bad behaviour. I'm not saying you cant open 20 tabs if you want, but it if you get that issue with tabs open then that is most likely the cause.
