Integrating WP into existing site

Hi Folks,

I’ve followed these instructions, wanting to have a WP blog show up in my site, and am not having any luck. Here is my result:

https://www.fionnafloral.com/blog.php

The blog itself is here:

https://www.fionnafloral.com/blog/

At the top of the static page I’ve pasted:

<?php define('WP_USE_THEMES', false); require('blog/wp-blog-header.php'); ?>

The loop code I’ve pasted into the body of the static PHP page above is:

<?php
			if ( have_posts() ) :
				// Start the Loop.
				while ( have_posts() ) : the_post();

					/*
					 * Include the post format-specific template for the content. If you want to
					 * use this in a child theme, then include a file called called content-___.php
					 * (where ___ is the post format) and that will be used instead.
					 */
					get_template_part( 'content', get_post_format() );

				endwhile;
				// Previous/next post navigation.
				twentyfourteen_paging_nav();

			else :
				// If no content, include the "No posts found" template.
				get_template_part( 'content', 'none' );

			endif;
		?>

Suggestions most appreciated! Thanks, Dan
