Error when trying to change subdomain

[clanuis]

Hello, my subdomain is: clanuis.exofire.net

I get an error when trying to change the subdomain in the x10 account management panel:

An Error Has Occurred

Whoops, it appears that there was an error modifying your domain. The errors are listed below.​

• Whm error: account server id does not match the package's server id. in theory, this should never happen. :-( (code modifydomain_2)

You may attempt to correct any errors that occurred after continuing​

What is wrong?

That's rare. Try changing it again, if you still can't, PM me the subdomain you're trying to change to, and I'll make the change.
