I have created a subdomain, sub.example.com. It has been added to the dreamhost DNS. Up to now everything was ok. I have then deleted this subdomain but the fact is the entry is not removed from the DNS. When I later tried to recreate my subdomain sub.example.com, I got a message error saying:
Can’t add domain: already in our DNS system.
Therefore I am stucked. Is there any way to override this behaviour (should I stay bug?) or should I contact the dreamhost support
Thank you for your help
