Yes, that was the problem.

In file ~/.config/lxqt/panel.conf, the line
    plugins=desktopswitch, quicklaunch, taskbar, tray, statusnotifier, mount, volume, clock, showdesktop
should have been
    plugins=mainmenu, desktopswitch, quicklaunch, taskbar, tray, statusnotifier, mount, volume, clock, showdesktop

Discovered by comparing ~/.config/lxqt/panel.conf with ~guest/.config/lxqt/panel.conf

It was very useful having a guest account.

I wonder how this file got changed a few days ago.
