Well, I did that command on : /var/www
Restart apache. (command was : chown -R www-data:www-data /var/www )
All directories Cxxx and files are under www-data.
So now, it should be better, but I do not know how to verify it is better.
I may restart Lucee, to see a result ?
Directory “/var” is under "root root " , I assume , it should be left as that ?
Thanks for your assistance.
Pierre.
