Question:  I press “On Air”, select “Stream on Page you manage” but it does not show my pages.

Answer:  It very seems you don’t accept permissions for JustBroadcaster.

So it’s easy steps how to resolve it

Step 1

Goto Facebook->Settings->Apps or jsut click on this link  https://www.facebook.com/settings?tab=applications

Step 2

Found JustBroadcaster and remove it

 

Step 3

Open JustBroadcaster for Facebook and press “On Air”. The app will open a browser and it will ask you permissions for JustBroadcaster.

Please press “OK” button for all permissions.

 

Step 4

Select your pages or group and press “Start now”.

Be aware: you can stream only to you managed pages or group.
