The issue I am facing:
Can't add domains to blacklist
Details about my system:
Raspberry Pi 4 B 2GB RAM
What I have changed since installing Pi-hole:
I added a few domains and RegEx patterns, but when I see an ad domain that got by in the query log, it says:
"While executing INSERT OR IGNORE:
attempt to write a readonly database
Added 0 out of 1 domains"
And the domain is not blacklisted.
