*** [ DIAGNOSING ]: Operating system
[✓] CentOS Linux 8 (Core)

As noted in the thread below, Centos 8 is not a supported OS, as it lacks some of the dependencies required for Pi-hole. Centos 8 is missing a package, php-json ; you will need to install that for the web interface to work.

Databases unable to read anything blocking isnt working either

Please follow the below template, it will help us to help you! 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] Debug Token: [vfsqnu4jd9]
