<?php
/**
* The base configurations of the WordPress.

* Secret Keys, WordPress Language, and ABSPATH. You can find more information
* by visiting {@link http://codex.wordpress.org/Editing_wp-config.php Editing
* wp-config.php} Codex page. You can get the MySQL settings from your web host.
*
* This file is used by the wp-config.php creation script during the
