I recently set up a new 5.5.8 smart mirror in our network. Our old mirrors are running 4.12. When someone selects the clone dialog under Actions from one of the old mirrors, the push-url command is displayed at the bottom of the dialog. When the new mirror is selected, the push-url window goes away. It's almost as if the server does not see it as a read-only mirror. Any ideas (bitbucket.properties entry I'm missing?) what might be causing this issue?
