What do you mean? Did you already fix anything?
First, I still to to log after I register.
Second, when I logout, I get this unfriendly error:
{"error":"invalid_grant","error_description":"The provided access token is invalid, or was issued to another client."}
Third:
Firefox still saved just my username.
Why do you want me to clean my browser, I keep it pretty clean, and I just reload your page, so I should have the latest version of your app.
