Keep getting asked to put in Facebook password, can't delete the account in the settings.
Ever since the recent update I keep getting a pop up asking me to enter my facebook password. I've been told to go into my settings and delete the Facebook account but it won't delete. Facebook says this has nothing to do with them because it's not the Facebook app. I have deleted the app it's self many times. I can't even log into the app because that pop up keeps coming up. So I haven't downloaded it again. And I'm still getting that pop up, even when I'm writing this it's popping up asking me to put in my facebook password.
I need to know how I can delete the account in my settings, because it won't delete when I hit "delete account".
