WordPress Content OUTSIDE Giving Index

I’m trying to implement the solution provided in this post to deliver WP content to pages outside of WP’s scope. But for some reason WP is giving me the index page no matter what. Check it out:

PHP: https://www.digitalgoof.com/bio/bio_index.php
TXT: https://www.digitalgoof.com/bio/bio_index.txt (the source)

My WP installation is to /journal and that stuff all works fine. It’s almost as though WP is erroring out and just serving up the index page. What can I do to gain access to WP functions on these other pages? My preference is to refrain from moving WP to my root web directory.

Thanks!
