If you missed the minor update and are now upgrading from 3.5.x to 4.4.x you may find the GUI now shows some features are not enabled. This is because we simplified the way we package Linux ISO’s.
This can easily be resolved without contacting support.
Simply SSH into your Virtual Appliance and run the following command
yum install -y appliance-live-environment-xbmr-linux-release && restart_services
