Recently I added firewall rules using ISPConfig->System->Firewall. And they worked fine, it seems. Then I rebooted the server and now the "server" is missing from ISPConfig, which means I cannot add new sites/databases etc. Then I removed the firewall instructions and it did not make any changes. I used the template given by the dedicated server provider to install Debian 7 with ISPConfig 18.104.22.168p1. So I did not configure the bindings or anything manually. Any way to solve this issue without having to re-install ISPConfig?
