Use 'old trick'. Switch web and then switch back.
Does not work - it installs everything for another server, but it still says nginxproxy in Kloxo - it seems slave is using setting from master server.
Manual trick also does not work...
[root@backup httpdocs]# lxphp.exe ../bin/common/misc/changedriver.php web nginxproxy
This is a Slave Server. Operate it at the Master server.
