Hello,
With one of my forms, the ActionController::InvalidAuthenticityToken is occurring after the form is sent to the proper controllers "create" method. The thing is that there actually is a valid authenticity token included and the error only occurs in Firefox. Other browsers work fine.
I tried to skip the verification of the auth token. It helps, which indicates the forms is being sent correctly, but other things are then not working such as flash messages. So the problem is probably deeper and has to do something with sessions.
Anyone has ever encountered something similar?
Thank you!
