Display user name when loging in with Facebook instead of fb-738498327
I need help in getting the user's name displayed instead of Fb-98983749873 when a user logs in with his facebook account. I'm talking about the top header black bar where it says "Welcome Fb-98983749873 ".. Would be great if it could say for example "Welcome Bob Smith"...
I've been trying to do this for a week now
Please help !
