I set up jitsi-meet web few weeks ago. Recording and live streaming buttons are shown as disabled.
I edited /etc/jitsi/meet/mydomain-config.js file and set;
fileRecordingsEnabled: true, // If you want to enable file recording
liveStreamingEnabled: true, // If you want to enable live streaming
I also checked interface-config.js and recording and livestreaming buttons are added in TOOLBAR array.
In previous versions i have not recognize such kind of disabled buttons. I guess it is a new update.
Anyone out there having such kind of experience.
