A Solid Guess : Its because you have allowed this application(app id) in past so you just log-in to your facebook accout - go to your application and remove that app. so next time it will ask.

you tried another unm and pwd then also its not shown properly? then I don't have solution right now..will have to search for that...but meanwhile you can do one thing make use of another app id or unm/pwd and check your code!

and then to resolve your error (I am guessing cause didn't got such issue yet)..while log-in the window appears is from the facebook default app..so this all problem happens..to remove that and call your own pop-up dialog see My Answer Here.

Thanks.
