When I try to map a new domain of ours to our website, I'm getting the error "Other subdomains of this domain are registered to another user at WordPress.com so you can't use it for your site. Only that user can register other subdomains."
I've never had this problem when mapping domains before, but I'm using a new domain provider (LCN.com) instead of my usual (123-reg.co.uk).
We've recently purchased this domain http://www.greenhouse.uk.com and haven't used it alongside any other blogs.
Does anyone know what the problem might be?
Any help greatly appreciated!
The blog I need help with is greenhousebangor.wordpress.com.
