clickatell sms api

I set debug to true and https to false for sms component: ‘debug’ => true, ‘https’ => false like this

‘components’=>array(

‘cache’ => array( ‘class’ => ‘system.caching.CFileCache’, ),

‘sms’ => array(

    'class'=>'ext.ClickatellSms.ClickatellSms',


    'clickatell_username'=>'XXXXXXX',


    'clickatell_password'=>'XXXXXXXXXXXX',


    'clickatell_apikey'=>'XXXXXXXX',


                


    'debug' => TRUE, 


    'https' => FALSE,

),

)

Mais je recois toujours le meme message d’erreur: "Undefined variable: https " quand j’essai d’envoyer un message.

comment puis-je regler cela?
