@ronivay Ok. In between jobs I did a new VM install of debian 11 and on it the XO community version.
Version numbers now:
xo-server 5.100.1
xo-web 5.101.1
I seem to have everything working again. Thanks for the help and tip. Now it seems really solved. 🙂
If I come across anything else, which I don't think I will, I will report back.
Greetings and thanks,
Jan
