WordPress site seems convinced that it's still at its old URL

Question

I had a demo environment set up in /subdirectory/ and then moved it to my root directory to make the site live.

• Used the wp migrate db plugin to export my database with the new paths, then replaced all the database tables with my new export.
• I did a search and replace in PHPmyAdmin and replaced /subdirectory with /, just to make sure nothing was missed.
• Copied all the content from /subdirectory to my the site's root

Upon doing this, my site worked at the root URL, however, I noticed that the bloginfo('template_directory'); and get_template_directory_uri(); functions get the old URL! (/subdirectory/wp-content/themes/my-theme/).

If I remove the /subdirectory/ files, the site doesn't load (I just see a blank page).

I went to my index.php to check on where wp-blog-heaer.php was being loaded from, making sure that it was referencing my root directory.

I also added

update_option('siteurl', 'http://www.mysite.com' );
update_option('home', 'http://www.mysite.com' );

to both wp-config files.

I even used the Search and Replace Database Script recommended in the Wordpress Codex to make sure I didn't miss anything in the database like serialized strings.

Can't decipher why my site still thinks that it's in the old URL. Any ideas?

edit: My root .htaccess seems fine also. No mention of /subdirectory

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

# END WordPress

Silly mistake on my part,

At some point I defined my wp-content directories right in wp-config.

define( 'WP_CONTENT_DIR', '/home/user/public_html/site/subdirectory/wp-content' );
define( 'WP_CONTENT_URL', 'http://www.seocial.ly/site/subdirectory/wp-content' );

Completely overlooked this when editing my wp-config.
