Can't Connect Database By Using Codeigniter Framework ?

[i3oomiiz]

My website is using CodeIgniter Framework but it show error:

A Database Error Occurred

Unable to connect to your database server using the provided settings.

Filename: core/Loader.php

Line Number: 346


What is this problem ?

my database config:

$db['default']['hostname'] = 'localhost';
$db['default']['username'] = '705008_i3oomiiz';
$db['default']['password'] = 'xxxxxx';
$db['default']['database'] = 'i3oomiiz_99k_onlineshopping';
$db['default']['dbdriver'] = 'mysql';
$db['default']['db_debug'] = false;
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre'] = '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;

put $db['default']['pconnect'] = TRUE; to $db['default']['pconnect'] = false; cause we disable mysql_pconnect() so you need to use mysql_connect() and you will be able to use it just fine
