WordPress: Error establishing a database connection

Question

This is my first time working with WordPpress.

I want to make it work on my localhost using xampp. I have followed the steps in the documentation and created a database but when I go to the URL localhost/database_name it gives me this result:

I have searched to solve the problem and I found that I don't have wp-config.php file in the database so I created wp-config.php using wp-config-sample.php and when I created it and tried to configure it again in localhost/database_name it gave me this result:

I have tried to make a new database with a new configuration also but nothing worked. How can I solve this?

Answer 1

I would recommend you to double check the hostname and database name to get it sorted out that way. Which host are you using? Delete your configured wp-config.php and let the browser create one for you - it will also validate your credentials during creation and ensure you'll get the right settings from start.
