Step 1 - Open File Manager

1. Log into the one.com Control Panel.
2. Click File Manager under Files & Security.

Step 2 - Open wp-config.php

The wp-config.php file is located in the directory where you installed WordPress.
Click on the wp-config file to open it in the editor.

Step 3 - Locate the login details

Usually, you can find the login details around line 20 in the wp-config file.
In this example the current details are:

define('DB_NAME', 'one_example_support');
define('DB_USER', 'one_example_support');
define('DB_PASSWORD', '********');
define('DB_HOST', 'one-example.support.mysql');

Step 4 - Update details

In the following example, you need to replace update_here with your own updated details.
You can find the current connection details in the one.com Control Panel under PHP and database settings.

define('DB_NAME', 'update_here');
define('DB_USER', 'update_here');
define('DB_PASSWORD', 'update_here');
define('DB_HOST', 'update_here');

Click Save in the upper left corner on your screen.
