DreamHost and CodeIgniter htaccess problem

[eluser]jprateragg[/eluser]
I'm on DreamHost and my site works fine. Here's my .htaccess:

Code:

RewriteEngine On

# Existing files and directories remain accessible
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.* - [L]

# Redirect the rest
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php?/$1 [QSA,L]
