trying now switching over from Debian to CentOS or in the later stage Rocky or Alma Linux.
I installed a test server on CentOS8 base.
On CentOS in the Webmin Server Part, Apache I can’t see the “Configure Apache Modules”. How can I see, in that case, which mods are activated and disable or activate mods there?
I think you may have to edit /etc/httpd/conf/httpd.conf, and manually add/modify/remove the LoadModule lines in there. Or Servers → Apache WebServer → Global Configuration → Edit config files
