If we want http and https at the same time, there is no problem! We write the following in wp-config.php
function isSecure() { return (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off') || $_SERVER['SERVER_PORT'] == 443; } $web_site = 'domain.gr'; $schema = isSecure() ? 'https://' : 'http://'; $web_site_url = $schema . $web_site; define('WP_HOME', $web_site_url); define('WP_SITEURL', $web_site_url);
