ERROR The Zone (soa) can not be changed. Please ask your Administrator if you want to change the Zone name This happens when logging in as client on a IDN domain, and try to access Records in DNS settings. php5-intl is installed so the domain is showed as IDN but cant save that since it is not allowed. If i replace the IDN with the punycode it works and can switch to record form and can change records. Clients dont understand this ofc. As admin it works as expected, no error. Version 220.127.116.11p6 and all patches installed. Is this a bug or something wrong with my system ?
