Hello, I do two operations on ISPConfig 1) Upgrade from 2.2.14 to 2.2.18 version of ISPConfig and system is working fine 2) Change the admin email of DNS from [email protected][email protected] ( in the Setting panel). Now I go to DNS Manager to manage my exist DNS there are some problem like below: - When I create new Domain, everything is done - When I add new record to the exist Domain, there is an error message "Invalid email [email protected] Moreover, zone file in /etc/bind/ is still exist but dns_isp_dns table doesn't contain it. How do I recover it and how do I avoid a disappearing when I add new record to exist domain. Urgent please!!!
