Domain "Not found" error

Hi all,

I’m running a WordPress Multisite with about 20 different website’s all with their own domainname (Domain mapping enabled). It works perfect, but only one domain keeps saying “not found”. This is the website that keeps saying “not found”:

http://www.managedwordpress.eu/inyourfacevisagie/
http://www.inyourfacevisagie.nl

The strange thing is that the /wp-admin on this domain actually does work. But if i try to access the website (domain or /inyourfacevisagie) i get an “not found” error.

All the settings for this domain are the same as on the other domains that work properly. The DNS of the domain is correct and points to the right IP-adress. Actually this website did work in the past, also on this network. But since today it stoped working and I dont know why. I allready set the domainname settings again, checked it twice, but nothing happened.

Can you guys help me solving this? Anyone have some advice for me?

Thanks!
