I have an Ubuntu 16.04 server with ISPConfig Version: 3.1dev. and a website where I installed WHMCS. Whenever a client stops paying, their accounts are removed from the clients list from the ISPConfig interface within a couple of months. After that, I can't restore their accounts. However, they still have their accounts on the WHMCS platform. Is there an option to change this configuration? and how can I retrieve a removed account?
I can not stress this enough: keep your systems up to date !! Ubuntu 16.04 hasn't had any security updates in almost a year unless you are paying for ESM. And ISPConfig has had several security bug fixes in the past releases. So before continuing to read this reply, update your sh*t! I don't use WHCMS, but I suspect you can disable this in their software. ISPConfig does not remove them.
