Wordpress alongside CI

[eluser]nelson.wells[/eluser]
I've searched the forums for how to do this, and the solution (I thought) was told in this thread

http://ellislab.com/forums/viewthread/136673/

Like the poster in this thread, I have CI on the root and a blog folder on root as well. The URL to the blog should be www.domain.com/blog . My .htaccess is rewritten so that CI will ignore everything in the blog folder, but when I try to view individual posts or even the index of the blog (www.domain.com/blog/index.php), I get a blank page. The odd thing is that the Wordpress admin pages work (www.domain.com/blog/wp-admin). Any idea what I am doing wrong? Here is my .htaccess

Code:

RewriteEngine on

RewriteCond %{HTTP_HOST} ^apt.nelsonwells.net$ [OR]
RewriteCond %{HTTP_HOST} ^www.apt.nelsonwells.net$
RewriteRule ^(.*)$ "http\:\/\/google\.com" [R=301,L]

RewriteCond $1 !^(index\.php|assets|blog|images|dev|sitemap.xml|info.php|hi.php|red.jpg|blue.jpg|yellow.jpg|ee|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]
