We mentioned earlier WordPress stores all the database information and important settings in wp-config.php file. So you need to check this file and make sure that your database name, username, and host all the information are correct.

After that, you can find the file in the wp-includes folder. wp-includes folder located in the same directory where wp-content and other folders are located.

After accessing the file look for this line where you will find the database name, username, and hostname. Make sure that all the information is correct.

// ** MySQL settings - You can get this info from your web host ** //

/** The name of the database for WordPress */

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' );

You can find all this information from your hosting account. Login to your hosting account and match all the information with your database.

Check database host information

If your database information is correct in WordPress wp-config.php file but you see the database error then you need to check for the database host information. Because most of the time hosting providers use localhost as database host but some companies are not using the localhost as database host. They have a separate server for your database host. So you need to make sure that you are using the correct database host information.

If your hosting provider uses a separate server and you are using the localhost information then your website won’t be able to connect with the database. So contact your hosting service provider to get the right information.

Check for the database server is down

If you are using the right database host information, right database information but still face the problem then your hosting server may be down. If there is an error in your hosting server that can also be the reason for the database connection error. If there is too much traffic your hosting server can not handle then it goes down and you will face the database error. So make sure that your hosting server can handle traffic pressure.

Repair WordPress database

If you are seeing the message that “Database is unavailable” in your admin area then you need to repair your database. To repair your database add this line at the end of the wp-config.php file.

define('WP_ALLOW_REPAIR', true);

This code will repair your database. After repairing make sure to delete this code and save the file.

Rebooting web server
