DB-NAME‘ is your website MySQL Database name and ‘DB-USER‘ is the Authorized User to that database . Go to your website cPanel and click on “MySQL Databases” under “Databases“. There you can see the “Database” name and “Privileged Users“. Check these two fields with the “wp-config” file fields for the accuracy.

DB-PASSWORD‘ should be the MySQL Database password you chose when you were creating the database. If you can’t remember the password, you can simply create a new user with a new password and add it to the database. In most servers, ‘DB-Host‘ is ‘Localhost‘.

Check all the fields mentioned above for accuracy. If any of those fields are incorrect, your WordPress website will not function properly and may give the error message “Error Establishing a Database Connection“. If you have tried both of the solutions above and still can’t get rid of the error, it’s most likely caused by your website server. Contact your website hosting company for further assistance.
