The wpmu_new_blog hook is indeed deprecated and shouldn’t be used; however, it works because it runs after the new site has been initialized (see wp_initialize_site()) which means the database tables for that site has been created and filled with the default options. So because you are updating the site’s options like default_comment_status, then you should … Read more
get_page_by_path() will only search in the current site. If you need to find a page anywhere in your Multisite network, you can do something like this. function network_page_exists( $path ) { $args = array( // Max sites to retrieve. // If you have a large network, increase this. ‘number’ => 100, ); $sites = get_sites( … Read more
Perhaps this is because I’ve got WP set up as multisite. Yes, that’s right, WordPress disables the siteurl (and also admin_email) settings on a Multisite — see register_initial_settings() for the source. And I don’t know why they disable those (two) settings, but you can explicitly enable them like so for the url/siteurl setting, which for … Read more
Most plugins and themes don’t need to do anything special to be multisite compatible. Themes especially. So just because a theme or plugin doesn’t say it’s Multisite compatible doesn’t mean it isn’t. Sometimes plugins don’t behave well if you Network Activate them, but the workaround for that is often just to activate them on individual … Read more
I have resovled it myself. I have enabled sunrise in wp-config. Then add a script to sunrise.php to override HTTP_HOST. I made it dynamic since we have many websites. When you visit api.domainxy.com it automatically shows you domainxy.com. <?php $re=”/(?:api\.)(.*)/m”; $str = $_SERVER[‘HTTP_HOST’]; preg_match_all($re, $str, $matches, PREG_SET_ORDER, 0); if ($matches && $matches[0][1] != “”) { … Read more
Have a look at the following page and see if that answers the question for you… 😉 https://core.trac.wordpress.org/browser/tags/3.0.1/wp-includes/ms-default-constants.php
Yes, it’s possible to have 2 WP MultiSite installs on the same server – just treat them as 2 separate virtual hosts, put the WP files in separate folders and use separate databases (although you can use the same database server)
Export/Import like you would the data for any other WordPress install: On the development site: Dashboard -> Tools -> Export -> All Content (save file) Package up the Theme files as “theme-name.zip” Make note of any custom settings On the live site: Install the custom Theme `Dashboard -> Tools -> Import -> WordPress data file … Read more
Basically, it turns out you need two dedicated IP addresses, or a third vhost. IP Address You could use two IP addresses and do something like this in your apache configuration: #IP address for WP NameVirtualHost 12.34.56.78:80 #For everything else NameVirtualHost *:80 Then, make sure the VirtualHost for WordPress is declared thus: <VirtualHost 12.34.56.78:80> and … Read more

Right under where it says ServerName example.com you should add another line like this: ServerAlias *.example.com You might have already done that, but it was the only thing missing from the list of things you had checked.
