To change the default web server port

[TomHsiung]

Hello, I downloaded and installed the latest stable PrestaShop. The install process was very straight forward without any issue. However, after the installation while I accessed the site via Safari, I got 400 bad request error. My apache2 web server use 80 port for http protocol and 50443 for https. I modified the /config/config.inc.php file at row "define('_PS_SSL_PORT_', 443);", to replace the 443 with 50443. However, after this modification, the issue remains.
