Unfortunately, this plugin is no longer maintained, even though it is still the best, safest and easiest way to ensure perfect redirection to to correct( sub) blog.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. ![](https://secure.gravatar.com/avatar/2dcae23b0df876a91b2a8e4a60177ec7b3974eefbbe348071bff32cfb3c9babf? s=60&d=retro&r=g) ### 󠀁[Works great](https://wordpress.org/support/topic/works-great-6695/)󠁿 [David Rychlý](https://profiles.wordpress.org/redoper/) April 25, 2020 Works great on versions 5.3.5 and 5.4. ![](https://secure.gravatar.com/avatar/5d3149599b88dd796720b6f681f34110491d3fccba500e50567f562df49412ce? s=60&d=retro&r=g) ### 󠀁[Error! 403 Forbidden](https://wordpress.org/support/topic/error-403-forbidden-25/)󠁿 [dipendraksahay](https://profiles.wordpress.org/dipendraksahay/) March 24, 2019 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?
