我正在尝试将我的 codeigniter 网站上传到 cpanel 但是，我收到以下错误：
A Database Error Occurred
Unable to connect to your database server using the provided settings.
Filename: core/Loader.php
Line Number: 346
我已将所有文件上传到目录：/home/mycpanelusername/public_html/
和，
database name = mycpanelusername_db_databasename
databae username = mycpanelusername_fajs
database password = mydbpassword
我授予了我的数据库的所有权限
我的 database.php 文件是这样的：
$db['default']['hostname'] = 'http://myurl.org';
$db['default']['username'] = 'mycpanelusername_fajs';
$db['default']['password'] = 'mydbpassword';
$db['default']['database'] = 'mycpanelusername_db_databasename';
$db['default']['dbdriver'] = 'mysql';
$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;
谢谢，如果不清楚请追问
