Domain Mapping: Domains Setting – empty of entries

Hello:

I have set up and tested Multiuser with WordPress 3.2.1 on a Hostgator shared account. My test (testblog.domain.com) tests ok, but I cannot get a second domain (second.com) to resolve to a WordPress site.

The site (second.com) was configured on the server as both a Hostgator ‘Addon’ and a ‘Subdomain’, and had some standard html (ie was a working website, not WP). I removed these settings in Cpanel, and made it a ‘Parked’ domain instead. I used ‘subdomain’ rather than ‘directory’ to set up the WP network, as this site was setup on the host as a subdomain.

The issue may well rest on the Hostgator setup, but I wanted to ask a couple of things here before persuing the fix over there:

1) When logged in as ‘Network Admin’, if I go to: ‘Sites’ both my primary domain (domain.com) and the 2nd one (second.com) appear. I have tried going to ‘edit’ and then changing the domain to both ‘second.domain.com’ and back to ‘second.com’. I could use some guidance on what is correct here.

2) if I go to: ‘Settings’ and then ‘Domains’, I get a WP settings page called:’Domain Mapping: Domains’. This has fields for

New Domain

Site ID
Domain
Primary

Is the site ID the same as the ‘Domain’ referred to above (in question 1)?

Also, no matter what I do on this page, I get no entries – it always looks the same, with fields, but no data. If I do a ‘Search’ even for my primary domain (domain.com) nothing happens. If I add a new domain here, it does not appear after I hit ‘save’. Should it not appear?

Any input into this is much appreciated by this WP noob.
