There was a problem creating the addondomain

[imbliang78]

When I attempt to add my own domain "blog.imbian.com"
it tells me "There was a problem creating the addondomain" and shows that "Error from park wrapper: blog.imbian.com is already configured. " But I have already deleted it since it didn't work.
Anybody could help me ?

Shouldn't blog.imbian.com be a subdomain of imbian.com, not an addon domain?

Add it in subdomains, not addon domains.
