New Post: SPGetCurrentUser not returning user information

Hello people. Sorry to bring this conversation up again, but I have the same problem, not solved with the current solution (regarding quotes).

Any other reason that can make the function not return any value?

var userName = $().SPServices.SPGetCurrentUser({
fieldName: "Name",
debug: true
});

if I have this inside an alert or use the var, it doesn't do anything!! how can I debug it?

Thanks in advance
