Multisite problem

I have WP running at the top level and my goal has been to run multiple sites from the backend.

However, the only one that is working is the one with the domain name pointing to the top level, where WP is installed.

On my server, Pair.com, you can only have one domain pointed at the top level.

Shopviewit.com seems to be working although it’s main job is to run a Miva shopping cart which is in a subfolder called mm5. It has been at the top level for a long time and I have thought about pointing it to mm5 but other links would break.

I now want andreehurley.com to show up but it won’t – I have hard-coded a index.html and put it in the directory and sometimes it shows up as andreehurley.com, other times as shopviewit.com/realestate/ (the directory I created on the server and in WP).

The backend is sort of ok:
http://shopviewit.com/realestate/queen-anne/

It looks the way I want it to look, but it should be andreehurley.com/queen-ann/ – with or without the www. This brings a 500 error.

I think that I have to have all the domains pointed to the top level and need to take the index.html out of the directory, but then I get the 404 page.

If I make andreehurley.com a primary, I get a user error.

Thanks,

Andree
