Multisite install in a subfolder won't work with www

Question

I have a domain - www.mydomain.com Inside there is a folder with Multisite install - www.mydomain.com/sites Multisite is installed with subfolders. I have a site, let's say - www.mydomain.com/sites/mysite.

Now, when browsing to www.mydomain.com/sites and to mydomain.com/sites (without www) - both work. When browsing to www.mydomain.com/sites/mysite - works well too. But - when browsing to mydomain.com/sites/mysite (without the leading www), it's being redirected to the main site - www.mydomain.com/sites instead to the specific mysite.

I figured out it may be related to WP multisite that is main site located in a subfolder, but couldn't figure out how to make mydomain.com/sites/mysite redirect to www.mydomain.com/mysite as expected.

p.s I use a fresh install of latest WP

Answer 1

Wordpress redirects to the URL you gave it when you set it up. So if you told Wordpress you domain was www.domain.com and typed into the browser domain.com it would redirect to www.domain.com. This is expected. The only way to change that is to change it in the database. You can find the URL in two places in the _options table. Field names are home and site_url.
