What Does the Error Mean?

If you are a website administrator and own a WordPress Hosting account, you have probably come across the Error Establishing a Database Connection error at some point.

Below, we’ve compiled a list of known solutions to the database connection issue that every WordPress administrator and end-user may encounter.

Solution #1: Check the wp-config.php file

If you have recently performed changes to your MySQL database via your Database Manager (such as modifying the password of your database) or your hosting account has been moved to a different server, then you will need to update the file wp-config.php as well.

wp-config.php (also known as the main configuration file) is probably the most important file in every WordPress system. It stores essential and sensitive information regarding your blog, such as the database connection settings and the security keys.

Open up the configuration file (it should be located in the root directory of your domain/sub-domain name). Once in the editor, look for the following four variables in your PHP code:

  • define('DB_NAME')
  • define('DB_USER')
  • define('DB_PASSWORD')
  • define('DB_HOST')

Double-check all four variables defined in the code and ensure that they match the database settings available in your Database Manager.
