Problem with setup of domains on multisite

Hi,

I have a problem on a multisite. For the sake of my client I will keep the URL anonymous here on this thread, however, I have granted you full access to the website, so you can take a look and maybe help me to find a solution to my issue.

Main Domain
My clients main domain is: http://www.example.dk.

Second domain
My client also have a english version of her website, which is http://www.example.dk/en This domain is currently set to show the content of the root where http://www.example.dk is installed.

Domain mapping
I have used WPMU's domain mapping plugin ( OF COURSE :smiley: ) to add the .com domain to the english website, so that the content from http://www.example.dk/en is shown on http://www.example.com.

So far so good, it works as expected...

Issue
However, my client also have two other installations, http://www.example.dk/no and http://www.example.dk/se. These installations she want to show using the .com domain, like this:

http://www.example.com/no
http://www.example.com/se

Now, I can't map those domains, and when I go to administrate the installs and change the URL manually ( see the screenshot ), and then load the page. I just get an 404 error.

Let me know if I need to clarify something here :smiley:

Sincerely,
Mika
