Let's Encrypt: Call to undefined function get_domain()
short description
When trying to add a Let's Encrypt certificate for a sub-sub domain (e.g. www.test.example.com) I get the error below running /usr/local/ispconfig/server/server.sh .
The error does not occur using a domain containing less or equal 2 dots (because of not using the get_domain function in this case).
environment
Server OS: Ubuntu Server OS version: 20.04 ISPConfig version: 3.2 Beta 1
PHP Fatal error: Uncaught Error: Call to undefined function get_domain() in /usr/local/ispconfig/server/lib/classes/letsencrypt.inc.php:386
