Same here:
[root@odyn ~]# service iptables stop
iptables: Setting chains to policy ACCEPT: nat [ OK ]
iptables: Flushing firewall rules: [ OK ]
iptables: Unloading modules: [ OK ]
[root@odyn ~]# csf -x
csf and lfd have been disabled, use 'csf -e' to enable
[root@odyn ~]#
And still no CWP GUI with error 500. Admin any ideas?
