What do I wrong.

I have a question about : the domain mapper plugin. I installed it, and managed it, but somehow it is not helping to cloak the domain into the subdomain. Using a TurnkeyLinux.com Wordpress server with MU enabled afterwards, which works perfectly. And the MU settings are running the domains as subdomains. installed the contents of the plugin, put in the right IP and when connecting to i.e. sol.yourboost.nl I get perfect the website as subdomain presented. However when I activate the plugin domain-mapping the site under his domainname (solbusiness.nl) is disappeared while solbusiness.nl is pointing correctly to the IP 81.23.250.207

What am I doing wrong.
Please help. :wink:
