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:


		'fb'=>array(

			'class'=>'ext.facebook.components.FacebookConnect',

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

			'appID'=>'My app ID',

			'appNamespace'=>'yapurlandia',

		),

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


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

array(

        'devappid'=>'My app ID',   

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

        'cookie'=>FALSE,   

));?>

I do not know why this is not working…
