I created a new subdomain for my site via the “[Add New Domain / Sub-Domain]” link in the DH control panel and everything worked fine. I then decided that I wanted to change the web directory of that subdomain so I edited it and made the changes. I then found that my subdomain would only work properly by including “www” in the address - this was not the case before. I then deleted the subdomain and have waited over 10 hours. I cannot recreate the subdomain with the same name because the dns records are still listed as A records under my primary domain. They are listed under the “Non-editable DreamHost DNS” section.
My question, finally, is - will these subdomain records be deleted after some time, or do I have to get someone from DH to manually remove them? Or is there any other way to solve this problem?
