If you get on local yii site this error:
Services_Twilio_TinyHttpException
SSL certificate problem: self signed certificate in certificate chain
You can fix it in this file:
\vendor\twilio\sdk\Services\Twilio\TinyHttp.php
Just find and add this parameter CURLOPT_SSL_VERIFYPEER => FALSE for CURL connection:
$opts = $this->curlopts + array( CURLOPT_URL => $url, CURLOPT_HEADER => TRUE, CURLOPT_RETURNTRANSFER => TRUE, CURLOPT_INFILESIZE => -1, CURLOPT_POSTFIELDS => NULL, CURLOPT_TIMEOUT => 60, CURLOPT_SSL_VERIFYPEER => FALSE );
Thats all. Happy SMSing…
