I Installed MQTT Binding, and immediately after the installation, HUE binding stops working. The OpenHAB log shows the following error while initializing my HUE thing:
No mqtt specific errors are shown.
Even after uninstalling the MQTT Binding and restarting OpenHAB, the error persists. I uninstalled and re-installed HUE Binding but the error remains. I needed to recover from a backup.
In Paper UI, the Extensions option in Menu is not shown.
My setup: OpenHAB 2.0 running on Raspberry pi3, ubuntu-mate 16.04
