The website works well for me, but I'm encountering the following problem for about a month :
when I launch the AF site on my laptop (Mac), it connects automatically and instantly to my FB account without any intervention from me (no login, password, nothing). I don't like this because it's a potential security problem if someone using my laptop is connecting to my FB account just launching Safari. But also, it's impossible to connect to another FB account from this laptop (for a family member for instance). Indeed, if I disconnect from my account, I have a blank page with this error message :
Revoke session not found 
And if I go back to the AF home page, it's reconnecting immediately to my FB account.
Any clue ?
