Children Pages pull 404, even after reset permalinks, no permissions change

You can check out the site I’m working on here: http://dev.blueox.com/wordpress

All pages are pulling correctly that I am working on, have been implemented with their varying template names. I was working within the dashboard, filling out custom post types, when the largest segment of the website seemed to create an error.

The pages in question are the children of the parent page “baseplates” found here: http://dev.blueox.com/wordpress/products/baseplates

Those children pages include:
http://dev.blueox.com/wordpress/products/baseplates/baseplate-sort
http://dev.blueox.com/wordpress/products/baseplates/fit-program

These two children pages have content in them, and do in fact exist. Also, every other children pages of a different parent works perfectly fine.

I am the only person working on the site, so it is unlikely there have been any permissions changes (and went to check, too). I’ve reset the permalinks to default and then back to post-name, and still no avail.

I also have checked my .htcaccess file and it 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

NOTE: After further exploration, if the permalinks are switched back to DEFAULT, the pages load. But once the permalinks are reset to POST NAME, the pages pull 404.

Any help?
