JError Unable to load Database Driver

After restoring a site with AkeebaBackup I got the following error.
JError Unable to load Database Driver

After some research the configuration.php missed the database information.
The following lines were not complete.

var $dbtype = ‘mysql’;
var $host = ‘xxxxxxxxxx’;
var $user = ‘xxxxxxxxxx’;
var $db = ‘xxxxxxxxx’;
var $dbprefix = ‘jos_’;

I filled those lines with my MySql info.

At the end of the configuration.php there is one more line that needs info.

var $password = ‘xxxxxxx’;

This is your database password. Non-encrypted.
