Addon Domain Bug

[edition2]

Hello, I have one addon domain. I went to add another domain and it says you already have 2 addon domains. I checked the domains page both on CPanel and X10hosting basic which lists only 1 addon. Any ideas?
UPDATE: I went to cPanel and tried to add the domain and it says the domain already exists in the apache configuration.

My guess is that the addon domain you are trying to add already exists in the apache configuration. I would recommend replying with the domain name you are trying to add on to your account and the server you are on (ex. xo7.x10hosting.com)
