Patrick O'Keeffe on "ERROR: Cookies are blocked or not supported"

I am getting this error when trying to login to my wordpress wp-login page ( I do not have an exposed form for users to use, just this page to access the admin area):

ERROR: Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress.

I have tried numerous fixes, from trying to re-save the wp-config file as UTF-8, Idea out the LOGGED_IN_COOKIE if function, updated wordpress to the latest version, deactivated new plugins and even tried renaming the entire plugins folder but can't get in.

Contact your hosting provider and ask them if they have set up the server in a manner it's filtering out the cookies that WordPress uses to handle logins.

Hello! heycameron

if you can edit wp-config.php please add this

set SITECOOKIEPATH , COOKIEPATH, COOKIE_DOMAIN, and ADMIN_COOKIE_PATH in wp-config.php:

define('ADMIN_COOKIE_PATH', '/');
define('COOKIE_DOMAIN', '');
define('COOKIEPATH', '');
define('SITECOOKIEPATH', '');

may this code will help you.

Hi there - I just came across this today and realized that when I updated the new URL, it didn't have the www in site name. If the URL is different, it will throw up that message.

That fixed it for me.
