WordPress MU

here's what i have so far

1) successfully installed MU along with multi domain plugin on my domain

2) successfully created a subdomain

3) registered a new domain

Both domains (1 + 3) share same DNS settings on the registrar as they are pointing to same server.

But notice how it's looking for "jtmediamarketingcom.xyz.." not "jtmediamarketing.xyz..."

how do I fix this?

Go double-check everything you typed in when you mapped the domain.

I did. I didn't see anything

as a hack, i added a subdomain jtmediamarketingcom. now when I go there via http://jtmediamarketing.com, i still get the same error

I get it redirecting to a non-existent blog, and back to the signup page.

Requests for the mapped domains should (in your dns settings) be directed to go to the MU install itself.

Hmm.. not sure if I follow. this is what i have in Apache config file

<VirtualHost 64.62.190.161>
        DocumentRoot /home/consumersreviews/www
        ServerName consumersreviews.org
        ServerAlias *.consumersreviews.org
        ServerAlias *.jtmediamarketing.com
        ServerAlias jtmediamarketing.com
</VirtualHost>

Why is this in there?

And what did you put in the backend menu when you domain mapped the blog?

1) not sure why, I thought it was a good idea. i removed it.
2) I have this in both master AND subdomain's domain mapping plugin setting - screenshot

No, I mean when you go to the admin area of http://jtmediamarketing.consumersreviews.org/

Visit the Tools menu and the Domain mapping sub-menu. What did you put in there?

same on both the main domain and subdomain (i.e. that screenshot is same for both)

That's your problem.

When you go to http://jtmediamarketing.consumersreviews.org/wp-admin/tools.php?page=domainmapping

you should be seeing an input box to put in the actual domain name you want to map.

I'm testing this exact plugin, and I know it works. :)

Hallelujah! Didn't realize I was at

/wp-admin/wpmu-admin.php?page=dm_admin_page

instead of

/wp-admin/tools.php?page=domainmapping

Thanks Andrea.

Oooh one other thing i wanted to ask..

is it possible to map say, "subdomain.jtmediamarketing.com" to "jtmediamarketing.consumersreviews.org"?

Yes. Use a cname instead of an A record.
