Unable to log into the game and link to my Facebook account

[hwong050]

I went all the way to lvl 316, and my account was linked with my Facebook account.

Unlike some other games, once you linked your game with Facebook, you are stuck with it.

Yesterday was fine. Today just suddenly the game can't link wirh my Facebook account.

Tried everything and nothing seem to work.....

Is it only me, other people have same problem?

Any idea how to fix it?
