New Network – Sub-domain site Does Not Exist ??

Hi

Multisite looks great – just have a problem with my first sub domain site …

I have installed the Network Multisite and the
Multisite Domain Mapping Pluggin and followed the directions
in Ottopress’s “WordPress 3.0: Multisite Domain Mapping Tutorial”

Things appear to be set up properly but my result is this:

( At the bottom it says that my sub-domain does not exist)

My main site is : https://reviewsworthreading.com

and the sub-domain site is:
buymobilewebsiteorg.reviewsworthreading.com

And the domain which points to that is:
https://buymobilewebsite.org

I have screen captured my settings:

The My Sites list :
https://www.sd5.info/DNS-08.jpg

(The sub-domain IS also in the dropdown)

The Sites list :
This shows the mapping.

The Domain Mapping page :

When you enter
buymobilewebsite.org
The result is:
https://www.sd5.info/DNS-12.jpg
and continued …
https://www.sd5.info/DNS-13.jpg

My DNS seems OK because the browser does go to reviewsworthreading.com but ?t doesn’t go to the blog at the sub-domain.

If I enter:
https://www.buymobilewebsiteorg.reviewsworthreading.com
into the broswer I get some advert page:
http.com
Below are sponsored listings for goods and services related to: http.com

OR sometimes:
https://www.sd5.info/DNS-14.jpg
The address seems to be missing the : after the http

Can anyone see what I have done wrong ?

Thanks.
