Diagnose XAMPP PHP Startup Issue

I need a fresh set of eyes to get my PHP project running locally under XAMPP. On both my machine and my teammate’s, Apache refuses to serve the pages: the server won’t start cleanly, and a “missing file” error pops up right on the web page instead of in the usual logs.

I’ll send you the complete codebase and my current `httpd.conf` and `php.ini` files. Your task is to spin it up in your own XAMPP environment, pinpoint whatever file or path is missing, and hand back the working configuration (or the corrected project files) together with a brief summary of what was wrong and how you fixed it.

If you can get the site loading—no server-start hiccups, no missing-file messages—we can talk about ongoing collaboration on new features and maintenance.
