This is how command “systemctl status named.service” and named.conf looks like :

Hi, I think error message saying it all, have you even read it?

I messed everything up!
I migrated a website from cpanel and i wanted to install a ssl cert and got some errors and i think i created a CA cert and deleted certs from webmin and Apache stop working, i restarted server and now not even webmin is not working.
How i restore back ssl cert for server?
