wordpress-mu-domain-mapping

Excellent, minimalistic plugin that still works 8 years after its last update.

The official WordPress Codex states: «In WordPress 4.5+, domain mapping is a native feature.» Unfortunately, this plugin is no longer maintained, even though it is still the best, safest and easiest way to ensure perfect redirection to to correct (sub) blog. The mentioned define('COOKIE_DOMAIN', $_SERVER['HTTP_HOST']); often results in wrong redirections to the main blog: In WordPress Network Admin: http://www.mydomain.org/ will likely make typing mydomain.org redirect to the main blog: https://example.com/?signup=new At the time of writing this review I am still very happily using WordPress MU Domain Mapping on WordPress MultiSite 5.7.1-alpha-50553, PHP 8.0.2. to ensure that my visitors end up on the correct blog (http, https, with and without www). In wp-config.php: define('MULTISITE', true); define('SUBDOMAIN_INSTALL', true); define('PATH_CURRENT_SITE', '/'); define('SITE_ID_CURRENT_SITE', 1); define('BLOG_ID_CURRENT_SITE', 1); /* Prevent redirection to /?signup=new */ define('NOBLOGREDIRECT', 'https://www.main-domain.com'); define('SUNRISE', 'on'); The defined COOKIE_DOMAIN will be set by this plugin to the correct url of all your blogs.

Works great on versions 5.3.5 and 5.4.

Hi, After following step-wise instruction, the result is the error message Forbidden You don’t have permission to access /wp-admin/network/settings.php on this server. Was the instruction applicable to WordPress Multisite Certified by Bitnami on Google Cloud Platform? Did I skipped some major steps? Regards

To me with the 4.9 is working

This is exactly what I was looking for. Very simple and useful tool. Thanks!
