Hi Till & Falko,
It might be possible that there is a bug in ISPConfig 2.2.30, because it is possible to add more then one co-domain with the same name (domain.tld).
For example: for the domainname
www.domain.tld, the co-domain domain.tld (without www) has been created correctly, but i can add that co-domain twice or even more then that. Although, the co-domains have the same name, they can be deleted individually. In stead of this behaviour, there should be an error message which says that the domain name already exists.
Can you have a look at this?
Thanks in advance!
