What Causes This Error?

This issue occurs when WordPress cannot connect to its database. Common reasons include:

• Incorrect database credentials (DB name, username, password, host)
• Corrupted database
• Server downtime or overload
• Damaged WordPress core files
• Hosting issues

Quick Fixes You Can Try

1. Check wp-config.php Credentials

Verify that the following values are correct:

define('DB_NAME', 'your_db_name');
define('DB_USER', 'your_db_user');
define('DB_PASSWORD', 'your_db_password');
define('DB_HOST', 'localhost');

Even a small typo can break the connection.

2. Repair the Database

Add this line to your wp-config.php:

define('WP_ALLOW_REPAIR', true);

Then visit:

/wp-admin/maint/repair.php

3. Contact Hosting Provider

If your server is down or overloaded, only your host can fix it. This is common on cheap shared hosting.

4. Restore Backup

If the issue started after an update or plugin install, restoring a backup may solve it instantly.
