Description
If your application doesn't have CSRF protection enabled, you'll see this error message when using forms that use CSRF:

This error message may be technically precise ... but it's not very useful because it doesn't explain how to solve the problem. The real solution is that you must set the framework.csrf_protection config option to true or null. So, should we update this error message? Or does this error happen in several different circumstances and we can't update it? Thanks!
