Installing WordPress onto an html site

I’m trying to install WP onto an html site.

I imported the site via iTheme’s BackupBuddy to it’s own wordpress directory in the root of the site (https://toddbaxterdawson.com), and want the WP site to show up instead of the html site.

I went to https://codex.www.ads-software.com/Giving_WordPress_Its_Own_Directory#Pointing_your_home_site.27s_URL_to_a_subdirectory and followed the directions, but it’s not working and I don’t know what I’m doing wrong.

My .htaccess (both root level and /wordpress/ level) reads:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /wordpress/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /wordpress/index.php [L]
</IfModule>

# END WordPress

~~~
My index.php (root) reads:

<?php
/**
* Front to the WordPress application. This file doesn't do anything, but loads
* wp-blog-header.php which does and tells WordPress to load the theme.
*
* @package WordPress
*/

/**
* Tells WordPress to load the WordPress theme and output it.
*
* @var bool
*/
define('WP_USE_THEMES', true);

/** Loads the WordPress Environment and Template */
require( dirname( __FILE__ ) . '/wordpress/wp-blog-header.php' );

~~~

My index.php (/wordpress/) reads:

<?php
/**
* Front to the WordPress application. This file doesn't do anything, but loads
* wp-blog-header.php which does and tells WordPress to load the theme.
*
* @package WordPress
*/

/**
* Tells WordPress to load the WordPress theme and output it.
*
* @var bool
*/
define('WP_USE_THEMES', true);

/** Loads the WordPress Environment and Template */
require( dirname( __FILE__ ) . '/wp-blog-header.php' );

~~~

Can anyone see what I’m doing wrong here?
