多站点域映射wp-admin登录循环

Question

I am trying to setup my multitsite with unique domains for each site. What Ive been trying: create the multisite with the specified config an .htaccess create sites (tried sub-domain & directory) test the sites work (they do) change the Site Address (URL) to the needed domain test the domain works perfect test the wp-admin dashboard this then starts the reauth login loop

if I login to the reauth link im stuck in the loop, if I change the url to wp-login then the correct cookie is created and login works until the cookie expires.

I have tried every proposed fix I have found in a whole weekend of searching: define( 'COOKIE_DOMAIN', $_SERVER[ 'HTTP_HOST' ] );, define( 'COOKIE_DOMAIN', '' ); and many many more none of them make any difference.

Only theme is 2016, no plugins etc etc

The problem is obviously cookies but I don’t know where to start, to see why.

Answer 1

i had a similar problem. this solution worked for me on:

• wordpress 4.7.3
• multisite (sub directory) network
• native domain mapping (no plugin)

solution: add the following to the wp-config.php file

define( 'ADMIN_COOKIE_PATH', SITECOOKIEPATH . 'wp-admin' );

right beneath the /* Multisite */ configurations

define( 'WP_ALLOW_MULTISITE', true );
define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', false);
define('DOMAIN_CURRENT_SITE', 'website.com');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);
define( 'ADMIN_COOKIE_PATH', SITECOOKIEPATH . 'wp-admin' );
