So here is what I'm trying to accomplish.
I have a domain name registered with GoDaddy and Google Apps running on it. And I have a hosting account with CPanel on another domain.
Let's say the domain is mydomain.tld and the host is on sub.otherdomain.tld. Also assume that Wordpress MU is installed in the directory ~/public_html/wpmu/.
What I want to achieve, is have Wordpress MU blogs accessible through blogs.mydomain.tld/blog_name without the ugliness of forwarding.
I tried different things, each one ending up with different errors.
The closer to the solution I could guess was trying to map blogs.mydomain.tld to a subdomain on the host pointing to the Wordpress MU folder, using an add-on domain on CPanel.
I believe the problem here lies somehow in the initial installation of WPMU where I declared that WPMU is on blogs.mydomain.tld. I got a 500.
I'd really appreciate it if someone could help me with this!
