What is a Database?

A database is software that makes it easy to store, organize, and retrieve data into other software.WordPress utilizes a database to store all your content and other data.

Every time someone visits your website, WordPress connects to the database.

For connecting to the database, WordPress requires the following information.

  • Database Name
  • Database Username
  • Database Password
  • Database Server

WordPress stores this information in the wp-config.php file. This wp-config.php file is the WordPress configuration file.

WordPress will fail to connect to your database server if any of these values are incorrect.

With this step-by-step troubleshooting, let us see how to fix the Error Establishing a Database Connection issue in WordPress.

Verify Your WordPress Database Credentials

Wrong database credentials are the usual reason for database connection errors in WordPress.

Have you migrated your WordPress site to a new host recently? Then this could be the most likely reason.

The wp-config.php file saves your WordPress database credentials.

This WordPress configuration file holds critical WordPress settings.

To check the values in the wp-config.php file, log in to the DirectAdmin control panel.

File Manager DirectAdmin

Click on the File Manager under System Info & Files section.

Now open the public_html folder.

Edit File DirectAdmin

Mouse hover on wp-config.php and click on the Edit File.

Take a look at the following lines in your wp-config.php file.

define( ‘DB_NAME’, ‘database_name_here’ );
/** MySQL database username */
define( ‘DB_USER’, ‘username_here’ );
/** MySQL database password */
define( ‘DB_PASSWORD’, ‘password_here’ );
/** MySQL hostname */
define( ‘DB_HOST’, ‘localhost’ );

It would be best to make sure that the Database Name, Database Username, Database Password, and Database Server are correct.

You can verify this information from your DirectAdmin dashboard.

MySQL Management DirectAdmin

Log in to your DirectAdmin account and click on MySQL Management under the Account Manager section.

Database List DirectAdmin

You can now see the MySQL Management page with all the Databases listed.

From here, click on the database name associated with your WordPress website.

You can toggle hide and show on clicking the eye icon.

You can copy the password to your clipboard as well.

Now click on the Change button, and the database password will update.

Have you confirmed your database name, username, and password? You can now modify that information in your wp-config.php file if needed.
