== Unable to Connect to the Database: Could Not Connect to MySQL ==
If during or after installation, you received an "'''Unable to connect to the database'''" error, verify that you have entered your MySQL/MariaDB database details correctly. The installation script will not allow you to continue unless the details are correct. Note that you are not expected to create a password for the database during installation - the error may then be due to entering a password which doesn't exist:. 

If the failure occurs after moving your site to another host, check the following items of your ''configuration.php'' file. The normal database settings are the following:
<pre>
var $dbtype = 'mysql';
var $host = 'localhost';
var $user = 'user_with_database_access';
var $db = 'the_actual_database_name';
var $dbprefix = 'table_prefix_';
</pre>
