Are you stuck in a frustrating login loop with WordPress Multisite? If you’re seeing the error message: “Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress,” don’t worry—you’re not alone. This issue often arises due to domain mapping in Multisite installations. Here are some effective solutions to get you back on track:
Solution 1: Update Your wp-config.php File
Add one of the following lines to your wp-config.php file:
define('COOKIE_DOMAIN', false);
Or:
define('COOKIE_DOMAIN', $_SERVER['HTTP_HOST'] );
Solution 2: Clear Session Tokens
Navigate to PhpMyAdmin and go to wp_usermeta. Delete the meta_value for session_token.
Solution 3: Additional Configurations for Multisite
If the above solutions don’t work, try adding these lines to your wp-config.php file:
define('ADMIN_COOKIE_PATH', '/');
define('COOKIEPATH', '');
define('SITECOOKIEPATH', '');Solution 4: Check Browser Settings
Sometimes, “Cookies Blocked or Not Supported” might be related to your browser settings. Ensure that cookies are enabled in your browser. You can usually find this option in the privacy or security settings. Additionally, try clearing your browser cache and cookies, as this can resolve conflicts that might be causing the login loop. If you’re using browser extensions, consider disabling them temporarily to see if they are interfering with the login process.
