问题 I've used Pusher API to put a simple push notification in place. I've tested everything and Pusher works on my localhost . When I put the same code on a live website, Pusher doesn't publish my message. That's interesting to note that if I push from localhost I can see the message on the live version. It seems that I have no problem subscribing to a channel, but the problem is that I cannot publish a message on the channel. This is my code: // Create pusher event $pusher=Yii::app()->pusher;
