The CSRF token is invalid. Please try to resubmit the form

Question

I\'m getting this error message every time I try to submit the form:

The CSRF token is invalid. Please try to resubmit the form

Answer 1

I had the same error, but in my case the problem was that my application was using multiple first-level domains, while the cookie was using one. Removing cookie_domain: ".%domain%" from framework.session in the config.yml caused cookies to default to whatever domain the form was on, and that fixed the problem.
