Error Establishing a Database Connection ​

This error means that WordPress is unable to connect to its database. It's usually caused by incorrect credentials, database corruption, or a temporary server-side issue. Follow the troubleshooting steps below to identify and resolve the problem.


1. Verify the database credentials in wp-config.php ​

Start by checking the credentials stored in your WordPress configuration file.

  1. Log in to your OS Cloud panel.
  2. Go to the Websites section, select your website, and open the File Manager.
  3. Navigate to your WordPress root directory (usually /public_html/).
  4. Open the wp-config.php file for editing. You'll find entries like this:
php
define('DB_NAME', 'your_database_name');
define('DB_USER', 'your_database_user');
define('DB_PASSWORD', 'your_database_password');
define('DB_HOST', 'localhost');

2. Verify the database details in the panel ​

Once you've reviewed the credentials in wp-config.php, make sure they match the actual database details in the panel.

  1. In the panel, go to your website and select Databases.
  2. Confirm that the values for DB_NAME, DB_USER, and DB_PASSWORD in wp-config.php match an existing database in the list.

If any of these details don't match, update them in wp-config.php to reflect the correct database name and user.

Tip: You can also create new database users under the Database users section if needed.


3. Reset the MySQL user password ​

If the database details look correct, the issue is most likely the password. In that case, reset the MySQL user's password and update it in wp-config.php.

  1. Go back to the Database users section.
  2. Select the user whose password you want to change.

  3. Scroll down to the Database access section.
  4. Click the kebab menu (three vertical dots) on the right and select Edit privileges.
