FB.getLoginStatus never fires the callback function in Facebook's JavaScript SDK

Question

The simple thing of calling FB.init (right before ) and then FB.getLoginStatus(callback) doesn\'t fire the callback funct

Answer 1

Yet another possibility for FB.getLoginStatus not firing its callback is when using a "test" user account that has not been authorized to view that application. Its pretty bad that facebook doesn't give you any error messages. I have also seen failed callbacks on bad appIds and redirectUrls.
