Yes, I tried fixing it adding the following to wp-config.php:
define('WP_HOME','https://15MBruselas.com');
define('WP_SITEURL','https://15MBruselas.com');
But it seems not to work.
UPDATE: if I remove the prefix www. to an url, it doesn’t work. So I log in to PLESK, and check this parameter on my domain -> navigation starts working again.
BUT /wp-login.php still doesn’t work
