Need help to get plugin working

Hi there

I need some help. I have created a new multisite. My domain is bizlocalizer.com. I have installed supporter and domain mapping. Everything is working fine. It is easy to create new sites. The only thing that I can't get to work is my domain mapping. I have tried everything.

Here is a run-through of what I have done so far and my setup:
Multisite Domain : bizlocalizer.com
Domain Registrar : Godaddy
Hosting Company : Media Temple
Hosting type : shared
Dedicated IP : 70.32.70.137 (redirect to signup screen as rerquired)
Test domain : revup31reviews.com (does point to 70.32.70.137)
Content site for test domain : buyingpower.bizlocalizer.com (must display this site)
Actions taken on Mediatemple.net (after mapping did not work):
- Added domain to DNS
- Created a symlink

It is still not working. Before I did the Mediatemple actions, nothing was displayed. After I did the Mediatemple action, it gives a service temporarily unavailable error.

Could somebody please help me. I just can't get this working.

Kind Regards

Danie Meiring
