WordPress MU

Hello everyone! I am new to MU. I have done many standard WP installations but this is my first MU install.
I got my WordPress MU installed and everything looks good. However, When I create a new blog it creates it as a subdomain (which is what I wanted). But the subdomain doesn't work : (

I have a reseller account with HostGator. They allow unlimited subdomains. The hosting package I created is set to allow unlimited subdomains as well. I have spoke with HostGator support and the person I spoke to did not have much knowledge about WordPress MU.

My question is simply what am I doing wrong? I did the WordPress MU install and everything appears to be working fine. But when I go into the SITE ADMIN >>> BLOGS >>> ADD BLOGS section of my WP MU Backend it allows me to create a new blog and give it a blog address (ie... newblog.nashvilleopenhouse.com) and it will say that the new blog was created successfully or "Blog Added". But when I try to go to my new blog internet explorer can't find the page.
Do I have to manually go into my hosting and set up a new subdomain each time I want to create a new blog? Can I set up my MU site to automatically do this for me?

Any suggestions would be much appreciated.

Thank you!!

Derek

You need to set up a wildcard on your domain DNS records and also ensure apache is configured to support wildcard domains too.

Thank you Steve! Is there some documentation somewhere that shows me how to do this?

No offense but the readme file included with the download would be a good start. :)

Google's pulls this up as well:

http://forums.hostgator.com/wordpress-mu-allowed-supported-t29592.html

I read the "read me" file as well as the link it referenced http://ma.tt/2003/10/wildcard-dns-and-sub-domains/

but I still am not extactly sure how to do this. Sorry... I am a newbie.

This helps:

mod rewrite is already on; register globals is already off. you won't have access to the httpd.conf on your shared machine, but shouldn't need it. hg does allow .htaccess overrides, and if you have trouble with your memory limits, ask support for help. you can also use php.ini if needed, but you probably won't need it.

I didn't know how to edit the http.conf file but it turns out that with host gator I can't : )
I just put a ticket in with hostgator support and they will set up wild card for me on their end.

That's why I gave you the extra link. :)

I'm on Bluehost and having the same trouble.. found this in help

Knowledgebase
Wildcard Subdomains or DNS
Top :: Bluehost Support :

Problem:

Do you support wildcard subdomains or wildcard DNS entries?

Solution:

Unfortunately we do not support wildcard subdomains or wildcard DNS records. If you require wildcard DNS, you may use another DNS provider such as dnsmadeeasy.com or editdns.net.

Keywords: subdomain domain DNS wildcard zone

Has anyone else tried using other dns providers or is it just easier to try another host ?

At the present stage I just wanted to try MU to see if it was right for me. Basically I'm looking to be able to have a main domain but have subdomains to help organise the content and for certain common info to be shared across.

Stay with bluehost.

If you want a wildcard subdomain

Go to your CPANEL

Subdomains

* .yourdomain

point to your WPMU install

worked for me
