Case Study: Error Establishing A Database Connection

Hi,

I have upgraded database with automatic upgrade tool of wordpress. After that when I tried to login in wordpress admin area. I have received this error message:

Database Error: Error establishing a database connection

Possible Solutions:

- Username and password information in your wp-config.php file is incorrect. Please check with PHPMyAdmin and correct it or reset it. Also make necessary changes in wp-config.php file.

- Make sure that you have typed correct host name in wp-config.php file.

- Your hosting service provider’s database server is down. Hence, take a support from your hosting service provider.

Thanks,

Shane G.
