Instead of get_site_url(), use get_home_url(). This will return the URL of the site you’re in. You can also get the URL of a different site in your Multisite network by passing that site’s blog_id (ie, $url = get_home_url( 2 );).

I believe that you have to go to the Network Admin (the ‘master’ admin), then Sites, then mouse over the site you wish to change, select Edit. So the process is not done from the sub-site’s Dashboard, but from the Network Admin dashboard. You may need to go into the Settings tab on the edit … Read more

Create a subdomain for each language, set the main site to English. Then use the plugin Multilingual Press to chain these subdomains together. It has an option to redirect the visitor to the correct single page too if it is translated on another subdomain (not sure if that is part of the free version). Subdomains … Read more
