This error occurs when WordPress cannot connect to your database. Follow these steps to troubleshoot and resolve the issue:

Step 1: Verify Database Login Credentials

1. Access your website files using an FTP client (e.g., FileZilla) or your web hosting control panel (e.g., cPanel).
2. Locate the wp-config.php file in the root directory of your WordPress installation.
3. Open the wp-config.php file using a text editor.
4. Check the following lines for accuracy:
   • define('DB_NAME', 'your_database_name'); – Ensure the database name is correct.
   • define('DB_USER', 'your_database_username'); – Verify the database username.
   • define('DB_PASSWORD', 'your_database_password'); – Confirm the database password.
   • define('DB_HOST', 'localhost'); – For most hosts, this should be localhost. Check with your hosting provider if unsure.
5. If any details are incorrect, update them and save the file.

Step 2: Check Your Web Hosting Server

1. Log in to your web hosting account.
2. Go to the control panel (e.g., cPanel, Plesk) and find the MySQL Databases section.
3. Ensure that your database is listed and is active.
4. If the server is experiencing downtime, contact your hosting provider for assistance.

Step 3: Repair the WordPress Database

1. Open the wp-config.php file again.
2. Add the following line of code at the bottom of the file:
   define('WP_ALLOW_REPAIR', true);
3. Save the file and close it.
4. In your web browser, go to:
   https://yourdomain.com/wp-admin/maint/repair.php
5. Select either Repair Database or Repair and Optimize Database.
6. Once the repair process is complete, return to wp-config.php and remove the line define('WP_ALLOW_REPAIR', true); to ensure security.

Step 4: Restart Your Web Server

1. If you have access to your web server, restart it to refresh the connection to your database.
2. If you're using shared hosting, contact your hosting provider and request a server restart.

Step 5: Restore a Recent Backup (If Needed)

1. If none of the above steps work, restore your website from a recent backup using tools like UpdraftPlus or your hosting control panel.
