Error [Xoops]: Unable to connect to database in file class/database/databasefactory.php line 34

So i go to the .php file i opened it with wordpad and i do not know what is the problem and what to do ???
Here is the .php file:
<?php
class XoopsDatabaseFactory
{

function XoopsDatabaseFactory()
{
}

/**
* Get a reference to the only instance of database class and connects to DB
*
* if the class has not been instantiated yet, this will also take
* care of that
*
* @static
* @staticvar object The only instance of database class
* @return object Reference to the only instance of database class
*/
function &getDatabaseConnection()
{
static $instance;
if (!isset($instance)) {
$file = XOOPS_ROOT_PATH.'/class/database/'.XOOPS_DB_TYPE.'database.php';
require_once $file;
if (!defined('XOOPS_DB_PROXY')) {
$class = 'Xoops'.ucfirst(XOOPS_DB_TYPE).'DatabaseSafe';
} else {
$class = 'Xoops'.ucfirst(XOOPS_DB_TYPE).'DatabaseProxy';
}
$instance =& new $class();
$instance->setLogger(XoopsLogger::instance());
$instance->setPrefix(XOOPS_DB_PREFIX);
if (!$instance->connect(xoops1)) {
trigger_error("Unable to connect to database", E_USER_ERROR);
}
}
return $instance;
}

/**
* Gets a reference to the only instance of database class. Currently
* only being used within the installer.
*
* @static
* @staticvar object The only instance of database class
* @return object Reference to the only instance of database class
*/
function &getDatabase()
{
static $database;
if (!isset($database)) {
$file = XOOPS_ROOT_PATH.'/class/database/'.XOOPS_DB_TYPE.'database.php';
require_once $file;
if (!defined('XOOPS_DB_PROXY')) {
$class = 'Xoops'.ucfirst(XOOPS_DB_TYPE).'DatabaseSafe';
} else {
$class = 'Xoops'.ucfirst(XOOPS_DB_TYPE).'DatabaseProxy';
}
$database =& new $class();
}
return $database;
}


}
?>




And at line 34 writes:
trigger_error("Unable to connect to database", E_USER_ERROR);
