Once again the Nethserver community shows how awesome they are! Thanks very much @dnutan for help. That page allowed me to tweak my Nextcloud just as I’d hoped.
Further clarification though perhaps on the cron job use. The default is webcron but that runs only when I visit a page. I’ve read that if I use cron my Nextcloud could or should be faster experience.
But what do I do to setup cron? Do I through the command line issue the following as per the wiki:
crontab -u apache -e
And paste this line:
*/15 * * * * /opt/rh/rh-php56/root/usr/bin/php -f /usr/share/nextcloud/cron.php
and then simply change in Admin panel to cron? Is that the only cron job I need to setup?
