Pi-hole v5.0 blacklist not working

[livpet]

Hello,

I installed Pi-hole 5.0 on RPI2 and everything seems to work fine except blacklist.

Expected Behaviour:

-perating system:Linux rpi2 4.19.58-v7+ #1245 SMP
Raspberry PI 2

Actual Behaviour:

I blacklisted the exact match yahoo.com and I updated gravity.

rpi2 ~ # pihole -q -adlist -exact yahoo.com
 Exact match found in exact blacklist
   yahoo.com

but the result is that any computer in the LAN can access yahoo.com

rpi2 ~ # dig yahoo.com
; <<>> DiG 9.10.3-P4-Raspbian <<>> yahoo.com

Thank you,

You have the blacklist entry yahoo.com assigned to group 0 (the default group).

But, seven clients clients (including the Pi) are assigned to Group 1, and group 0 is disabled.

This results in that domain blacklist being applied to a disabled group, so there will be no effect from that domain blacklist.

That is it. Thanks!
