Our VPS control panel provider, SolusVM found a security bug today, http://blog.soluslabs.com/2013/06/24/important-security-alert-whmcs-module/

So, Our ComfortVPS control function temporary disabled today(06/24/2013) for security reason

Hope SolusVM will fix it ASAP

Please open a ticket if you need reload OS or can't SSH reboot VPS.

Update: SolusVM Bug fixed on the afternoon of 06/24/2013
