The above message means that you created the trigger file and promoted the standby server to the master. Since the standby was running as the master, walreceiver was not invoked in the standby.

To start replication, you need to create the standby (taking the base backup from the master is required) and start it after you
*ensure* that there is no trigger file in the standby.

I hope this helps..
