When DevKinsta has downloaded the website from Kinsta, I cannot login into the wp-admin.
I see this error: Error: Cookies are blocked or not supported by your browser. You must [enable cookies] to use WordPress.

Already tried to restart browser (Chrome) after clearing cookies, check the site in Incognito mode, tried to login via a different browser (Firefox). Add this line to the wp-congif.php file: define( ‘COOKIE_DOMAIN’, ‘’ );

All is not working. How can we make this site workable after an pull from Kinsta to DevKinsta.

Hey @sgroeneweg, welcome to Kinsta Community!

Try to add these lines in wp-config.php and remove the one you added:

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