WordPress if you open a multi-site network, the default theme of the sub-site is the default theme of the current version of WordPress, WordPress 4.0, the default theme of the sub-site is “twentyfourteen”, if the “twentyfourteen” theme does not exist, the front page of the sub-site will be blank. twentyfourteen" theme does not exist, the front page of the sub-site to open is blank, the sub-site administrator needs to manually enable other themes in order to properly browse the sub-site front page. In fact, WordPress multi-site network can set the default theme, the setup method is very simple, just need to add a line in wp-config.php configuration on it.
Setting the default theme for multisite network subsites
In wp-config.php.require_once(ABSPATH . 'wp-settings.php');Just add the following code, where “your-default-theme” is the name of the default theme.
define( 'WP_DEFAULT_THEME', 'your-default-theme' );
After you set it up, the user registers a new child site, and by default it's the custom theme you set up.
PS: I personally believe that the WordPress multi-site functionality user experience is not good, blog this thing, functionality is not complex, if the expected scale is relatively large, it is better to take advantage of the independent development.
