You may see error messages such as: dnsmasq: extraneous parameter at line 37 of /etc/dnsmasq.d/01-pihole.conf failed! There are two options…

Typically, we release all three components of Pi-hole at the same time (Core, Web, and FTL), so you'll usually want to install version from the same "release." For example, we ran into some issues with v3.3 and dnsmasq compatibility with some systems, so some users needed to revert to v3.2.1 (Core and Web) but as part of the 3.2.1 "release," the latest version of FTL was 2.13.2. Because we version e…
