Check your database credentials

The first step is to make sure that your WordPress website’s database credentials are correct. These credentials include your database name, username, password, and host. You can find these details in the wp-config.php file. If the credentials are incorrect, update them with the correct values.

define('DB_NAME', 'database_name');
define('DB_USER', 'database_username');
define('DB_PASSWORD', 'database_password');
define('DB_HOST', 'localhost');

Check if your database server is running

Ensure that your database server is running and accessible. You can check this by contacting your hosting support or using tools like cPanel.

Check for server connectivity issues

If your website’s server is down or facing any connectivity issues, you will face this error. You can check your website’s status using tools like DownDetector.

Increase memory limit

If you’re facing this issue because of low memory, you can increase the memory limit in the wp-config.php file. Add the following code to the file:

define('WP_MEMORY_LIMIT', '256M');

Deactivate plugins

If the issue persists, try deactivating all your plugins. You can do this by renaming the plugins folder in your WordPress directory. If deactivating plugins fixes the issue, reactivate each plugin one by one to find the cause.

Repair database

If the above steps don’t work, you can repair your database using a plugin like WP-DB Manager or using WP-CLI commands. You can also repair your WordPress database by adding the following code to your wp-config.php file. Access the URL https://yourwebsite.com/wp-admin/maint/repair.php, and then click on the “Repair Database” button.

define('WP_ALLOW_REPAIR', true);

Contact your hosting support

If all else fails, contact your hosting support for assistance. They will help you resolve the issue.

Note: Before making any changes to your WordPress website, make sure to take a backup to avoid losing any important data.
