Fix WordPress Database Connection Error

Job ID: 40157947

Budget: ₹600 – ₹1,500 INR

My WordPress site suddenly throws “Error establishing a database connection.” I have already double-checked the wp-config.php credentials and they are correct, yet the front-end and wp-admin remain inaccessible. The site sits on shared hosting, and I can log in to both the hosting control panel and SSH without restrictions.

I need someone who can jump in, trace the root cause, and bring the site back online quickly. You will have full cPanel-style access, phpMyAdmin, and SSH to inspect MySQL service status, repair tables if needed, adjust server-side settings, or tweak WordPress core files. Once resolved, I’d appreciate a brief summary of what went wrong and any preventive steps I should take.

Deliverable: the homepage and admin dashboard must load normally with no database connection errors, and the fix should persist through a standard server reboot.
