Problem with creating sub domains for addon domains

[Przemek]

1) I have a account with domain: domain.com .
2) I created subdomain shop.domain.com
3) Then I created addon domain: domain.net

And here's the problem. When I try to add shop.domain.net I get error message: "Domain already exists". But it's shop.domain.com that exists and not shop.domain.net. How to create subdomains which are the same but differs only in the sufix (domain.com or domain.net)?

Dear Przemek,

You can not create subdomains for addon domains. The addon domain domain.net prevents the shop.domain.net from getting created. Remove domain.net and try adding subdomains. It will work.
