Expected Behaviour:
[blocking of ADs and able to see data in the web interface]
Actual Behaviour:
[Not seeing any data and get errors when accessing blocklists and trying to query logs. I see no logging at all when trying to tail from web interface]
Centos 8 is missing a package, php-json, so you'll need to install that for the web interface to work. 8 is not supported in the released code. There is a fix in development to be released next.
