Dns warning with latest update

The warnings have always existed in /var/log/pihole.log. A change to Pi-hole made them more visible by also printing them into /var/log/pihole-FTL.log and showing them on the dashboard.

Brief documentation for these warning can be found here:

https://docs.pi-hole.net/ftldns/dnsmasq_warn/

There is no way to turn off the warnings - they are generated by dnsmasq and Pi-hole shows them all.

To fix it so you no longer get the warning, see this thread:
