Finding your website's configuration file

Ce contenu n’est pas encore disponible dans votre langue.

Most website software keeps its database details, site address and main settings in one configuration file. You’ll need it when you move a site, change a database password, or fix “Error establishing a database connection”.

All paths below start from your website’s folder, for example public_html for your main domain. In cPanel’s File Manager, click Settings and tick Show Hidden Files to see files that start with a dot, such as .env.

Software	Configuration file	Database settings
WordPress	`wp-config.php`	`DB_NAME`, `DB_USER`, `DB_PASSWORD`, `DB_HOST`
Joomla	`configuration.php`	`$db`, `$user`, `$password`, `$host`
Laravel	`.env` (in the project folder, not `public`)	`DB_DATABASE`, `DB_USERNAME`, `DB_PASSWORD`, `DB_HOST`
PrestaShop 1.7 and newer	`app/config/parameters.php`	`database_name`, `database_user`, `database_password`, `database_host`
PrestaShop 1.6	`config/settings.inc.php`	`_DB_NAME_`, `_DB_USER_`, `_DB_PASSWD_`, `_DB_SERVER_`
OpenCart	`config.php` and `admin/config.php`	`DB_DATABASE`, `DB_USERNAME`, `DB_PASSWORD`, `DB_HOSTNAME`
Drupal	`sites/default/settings.php`	`$databases` array
Magento 2	`app/etc/env.php`	`'db'` section
WHMCS	`configuration.php`	`$db_name`, `$db_username`, `$db_password`, `$db_host`
MyBB	`inc/config.php`	`$config['database']`
phpBB	`config.php`	`$dbname`, `$dbuser`, `$dbpasswd`, `$dbhost`

On Ruachost hosting, the database host is localhost, and database names and users start with your cPanel username, for example cpuser_wp123. See Finding your database details.

Editing a configuration file safely

In File Manager, right-click the file and choose Download to keep a copy.
Right-click it again and choose Edit.
Change only the values between the quotes, and keep the quotes, commas and semicolons.
Click Save Changes, then reload your website.

If the site shows an error after saving, upload your saved copy to undo the change.
