addon domains problem

[zeng]

I used to add a domain of sinmap.com in cpanel, but there is no addon domains in the list. (Maybe I delete it somewhere else, is it possible?)

And when try to add it again, here is the problem:

There was a problem creating the addondomain. Show Details

Error from park wrapper: sinmap.com is already configured.

 

In the Subdomain page, I can see the sinmap.com.

but in dns setting page, there is only the main domain.

 

The pictures are the detail messgae I got in cpanel. what's the matter?
