Good Morning.
I installed Openfire 4.0.3 in Ubuntu 16.04, but when I want to load the plugin ofmeet from the management console openfire for video conferencing does not work. Get a green message saying that you have installed, to restart the service in order to see it, but reboot and nothing, does not appear. Please help !!!
That is a very old version (feb 2016) try this
