Urgent Database Connection Issue Fix

I'm urgently seeking a skilled freelancer to help resolve a database connection issue on my website hosted with Bluehost using PHP. I am unsure of the exact database type, but it is essential to restore connectivity as soon as possible.

Key Requirements:
- Diagnose and fix the database connection problem
- Experience with PHP and databases typically used with Bluehost
- Ability to troubleshoot and resolve issues without specific database type information
- Familiarity with common hosting environments and server configurations

Ideal Skills and Experience:
- Strong background in PHP and web development
- Experience with MySQL, PostgreSQL, or SQLite databases
- Problem-solving skills to identify and fix connection issues
- Ability to work quickly and efficiently to minimize downtime

I recently made changes to the website code, but after reverting them, the issue persists. Your expertise in resolving this matter promptly would be greatly appreciated.
