I have a multisite WordPress installation. When I am logged in as a super admin from the main website, and go to the dashboard from the main site into another site, it asks me for login details. When I enter the details, it gives me an error:
ERROR: Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress.
I also added code in wp-config.php:
define('ADMIN_COOKIE_PATH', '/'); define('COOKIE_DOMAIN', ''); define('COOKIEPATH', ''); define('SITECOOKIEPATH', '');
Still the problem occurs, even though cookies are already enabled.
