Facebook connect

Hi I am trying to use extension FacebookConnect to add a Facebook login in my web application, but code is not working.

I got the next code in config/main.php:



			#'appID'=>'My app ID',

			'appID'=>'My app ID',



And in user/login I´m using the next widget:

<?php $this->widget('application.extensions.facebook.FbLogin',


        'devappid'=>'My app ID',   

        'devsecret'=>'My app secret number', 



I do not know why this is not working…
