WPMU and Domain Mapping

When you mapped the domain to the site, did you check the box that says “Primary domain”?

Yes. Primary is checked on each domain. I’m pretty sure it was checked when setting up. URL Correction: https://usainsuranceonline.com

List out the other steps you did, as something is either misse dor not done right.

Did you follow all these steps?

OK! I got it. I had to log in as the site admin, then got to:
SUPER ADMIN > SITES then edit each domain to show domain.com instead of username.domain.com in the “DOMAIN https://: slot.

Thanks for the help!

Got another problem now. Some of the subdomains are listed on the search engines. When I changed to primary domain I get a 404 back to the main site from the subdomains. Not good to have thousands of 404 pages at one time.
eg: https://autoinsuranceandcalifornia.mywpblogs.info

I added a rewrite to the .htaccess file

RewriteEngine on
RewriteCond %{HTTP_HOST} doublediscountcheck\.mywpblogs\.info
RewriteRule (.*) https://www.doublediscountcheck.com/$1 [R=301,L]

However only the main subdomain is redirected. Any other pages still 404. Can you help me find the correct coding? Thanks a bunch.

That’s because you edited out the original subdomain….

That’s correct. Know of any good 301 redirect solution?

Without editing out the original subdomain, the domain mapping plugin handled the redirects for you. when set up properly.
