If you're the app developer, you may see a more specific error message, but generally that message means one of two things:

1. Your server returned a HTTP error code (usually 5xx)
2. You tried to send the user, after login, to a URL not allowed by your app configuration (though as an Admin of the app, you should see a more specific error message and Facebook error code in this case)
