Hi Ron!
Thank you for your help ... but ... it also don't work :-(
I try this with an other domain, but it always show the WP install domain.
SERVER Configuration:
* "myIP" is pointed to "http://wp-installation.com"
* "target-domain.com" ist pointed to "http://wp-installation.com"
* Site ID: 8
* Domain: "target-domain.com"
* Primary: No matter.
Question: I have a "root" domain "/" for the administration of the other blogs. Could this prevent the correct redirection?
