Hi,

and thats exactly the problem I have.
When I open my site with the www Zenphoto tries to reach the english site:
en.www.ralf-kerkhoff.de

If I delete the subdomain named en.www. I end with a 404 error.

So my guess for a solution was:
redirect wwww.ralf-kerkhoff to ralf-kerkhoff
This way I only need the en.ralf-kerkhoff for the english part.

Must be something specific to your server/host. Actually the www to the non www address redirection should not affect other subdomains at all.
