Hi,
We decided to drop support for custom Apache builds and thus. default Apache package from CentOS 8 repos compiled and hardcoded with suexec pointing to /var/www. There is nothing you should do really, just use FPM, it should cover all your needs, and it runs as server owner. Theoretically, mount binding /home to /var/www, could make things work but could require additional re-configuration.
How can I fix AWStats?
You can disable it in System Settings/Features and Plugins for now or install it from testing repos:
dnf --enablerepo=epel-testing install awstats
…however it will not work at the moment, as perl-Geo-IP is still missing.
