The $_SERVER[‘HTTP_HOST’] global will usually contain the domain/subdomain to which the current request was sent, but with a few caveats. In the context of a web request, the variable is set at the discretion of the web server and proxies, and Apache/Nginx may not pass that header along depending on their configuration – or may … Read more
You don’t need a rewrite rule in .htaccess to add www back in. Remove the rewrite rule, remove all the defines in wp-config and try to login. If that doesn’t work, delete permalinks in .htaccess to force them back to default. After you’re in, add the www in Dashboard>>Settings and save. Then reset permalinks.
Yes, this is possible (see https://wordpress.org/support/article/create-a-network/). For sub-domains you’ll need to confirm that your DNS has a wildcard entry for your domain. So, based on your root domain, this would work for: mysub1.multisiteroot.com, mysub2.multisiteroot.com, etc. If you wanted to us different domain names for subsites, then you’d need to have those domain names point to … Read more

As Sumit pointed out, the problem was in the old browser cache. The solution was to clear browser cache (or just add a query string after the address: http://my.new.domain/?random_string). Thank you.
Yes, instead of installing WordPress at root– example.com/— you’d create the “programs”, “sales”, and “learning” directories on the server and install a seperate WordPress instance in each directory. There is nothing special you need to do to make this work. I think you may end up happier if you create a network, though. Multisite, while … Read more
Like C C said some clarification would be helpful. If it helps, you can actually still use a subdomain and point the primary domain to it (the subdomain) using a flattened CNAME record. It is RFC compliant and functions the exact same as pointing the primary domain to an IP using an A record. Maybe … Read more
Yes. I just did an experiment on my own site to verify that changing those settings will redirect between www and non-www as you specify.
You also need to install the domain mapping plugin. http://wordpress.org/extend/plugins/wordpress-mu-domain-mapping/ http://ottopress.com/2010/wordpress-3-0-multisite-domain-mapping-tutorial/
