Override Site URL in wp-config.php

Add these two lines to your wp-config.php, where “example.com” is the correct location of your site.

define('WP_HOME','http://example.com');
define('WP_SITEURL','http://example.com');

Make sure that you include the http or https at the beginning and don't include a slash at the end. Reference: https://codex.wordpress.org/Changing_The_Site_URL
