I just created an account with my facebook account but the e-mail on that account is obsolete. I can't change it on my profil, just like my name/surname, and birthday.Thanks already !
You cannot change the email adress conected to an facebook created account. Unfortunately if you want to change your email you will have to
1. If your account is just connected to a facebook account try and disconected
2. If your account is created with facebook you will have to create a new one.
More info about disconecting an account from facebook here .
If you still need help try here .
