I recently installed Wordpress 3.3.1 on my Plesk server.
After struggling a bit to get the wildcard subdomains working everything is working great.
domain.com works &
Then I installed your domain mapping plugin and it seems to do what its supposed to.
newdomain.domain.com gets 301 redirected to newdomain.com
Unfortunately I'm getting the Plesk "Web Server's Default Page"
I have tried everything to get this to work. I spoke to the guys at my hosting company and they say the server is working fine and it seems the plugin is working fine they just aren't working together.
Any help would be really appreciated. I'm hoping its a small fix like the wildcard changes!
