External page title results in "Page Not Found"

When I enable any permalinks besides the ?id=xxx, external pages on my WordPress powered site result in the page title of Page Not Found.

Here is a link to an example page:
https://liveinthebible.com/resources/read-the-bible/

I am using the following code to include the WordPress structure on the external pages:

<?php
/* Don’t remove this line. */
require(‘../wp-blog-header.php’);
?>
