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 » Unfortunately, this plugin is no longer maintained, even though it is still the best, safest and easiest way to ensure perfect redirection to to correct (sub) blog.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!
