I installed WordPress MU Domain Mapping plugin through Network Admin, created the sites as sub-domains, mapped them in Tools > Domains (no primary specified), then checked off everything in Domain Mapping:
+ Remote Login
+ Permanent redirect (better for your blogger's pagerank)
+ User domain mapping page
+ Redirect administration pages to site's original domain (remote login disabled if this redirect is disabled)
+ Disable primary domain check. Sites will not redirect to one domain name. May cause duplicate content issues.
When I go to the sub-site admins, there's still Domain Mapping in Tools, which I don't want to be there, and it throws errors:
(above Dashboard link)
Notice: Undefined index: action in /var/www/html/islandhoodsites/wordpress/wp-content/plugins/wordpress-mu-domain-mapping/domain_mapping.php on line 373
(under Domain Mapping header)
Notice: Undefined index: path in /var/www/html/islandhoodsites/wordpress/wp-content/plugins/wordpress-mu-domain-mapping/domain_mapping.php on line 447
Active domains on this blog
Notice: Undefined index: path in /var/www/html/islandhoodsites/wordpress/wp-content/plugins/wordpress-mu-domain-mapping/domain_mapping.php on line 462
This shows two sites, subdomain.domain.com and subdomain.com, both with radio buttons, then a "Del" (Delete) link.
Below that, it shows:
* The primary domain cannot be deleted.
Warning! Primary domains are currently disabled.
Then a field to add a new domain with a checkbox to make it the primary... I'm totally confused and I don't want any of this on the sub-site admin!
