Diagnose PHP Blank Page Locally, Wordpress

I have a PHP site that refuses to load on any of my local stacks—the browser only shows a blank page with no error output. Before I move the project to a remote host I need someone to pinpoint why it will not run, get it working on your own machine, and show me the exact steps so I can replicate the fix on mine.

You will receive the full project folder as-is. I have not altered Apache, PHP, or MySQL settings beyond their defaults, and there are no visible errors in the logs I have checked so far.

Deliverables
• A working local copy of the site on your end (using the stack of your choice—XAMPP, WAMP, MAMP, or similar).
• A concise walkthrough of every change you make: configuration tweaks, missing extensions, file-permission fixes, or code corrections.
• Confirmation that I can follow your notes and launch the project without the blank page.

If we click well together I would like to keep you on board for future development tasks, so clear explanations and clean troubleshooting matter more to me than a quick patch.
