  1. Check wp-config.php File:
    • Verify that your wp-config.php file contains the correct database connection details (DB_NAME, DB_USER, DB_PASSWORD, and DB_HOST).
  2. Check Database Server:
    • Ensure that your database server is up and running. Contact your hosting provider to check for any server-side issues.

      • define('WP_ALLOW_REPAIR', true);
    • Visit http://yourdomain.com/wp-admin/maint/repair.php to repair the database.
  4. Check for Corrupt Tables:
    • Use phpMyAdmin to check for and repair corrupt tables in your database.
  5. Consult Hosting Provider:
    • Contact your hosting provider for assistance if the issue persists or if there are server-related problems.
