I've recently updated a site from EE 2.7.3 to 2.9.0. A client has pointed out to me that she can't log into the CP but instead get's the message:
This form has expired. Please refresh and try again.
I didn't get this message using Opera but managed to repeat the error using Firefox (on OSX).
After much fruitless searching around and playing with session settings with the CP, I tried disabling Cookie Consent and suddenly was able to log in using Firefox.
The problem is that I really need to have Cookie Consent enabled because of the nature of the client's business. So I'm wondering if anyone has had this same problem and has found a work-around?
I'm also using the latest version of Cookie Consent 1.1
