When I install Pi-Hole and afterwards FreshRSS, I get an error from Pi-Hole when calling http://192.168.0.100/freshrss (that says, that the page doesn’t exist).
in my case yes.
only difference i can think of is the version on time of install.
Pi-Hole was installed with v6.6(+/-), baikal with 6.14.
cups somewhere in between.
pihole -up on Pi-hole 3.X indeed breaks other web services, as it moves webroot from /var/www to /var/www/html.
The /etc/lighttpd/lighttpd.conf gets overwritten. I think changing the webroot back should be sufficient to make other web services run again.
To avoid these issues, we recommend that all Pi-hole 3 users update by using: dietpi-software reinstall 93
By doing so, a new (v4) setup variable will be placed to not install/update/config the webserver.
(Or Fourdee was there a reason to dietpi-software uninstall 93 first?)
Afterwards, you can use pihole -up without issues to update to higher versions and use other webservers (via dietpi-software choice) without Pi-hole always forcing a Lighttpd install .
