Joomla CSS missing in all but Home Page

I have been trying to setup a website for awhile here on Dreamhost. I noticed when I first setup the one-click install of Joomla everything works using the sample template.

It seems like something has changed maybe with URL rewrites as it prepends /index.php/ before all of <link rel=“stylesheet” …> paths to the CSS files.

The effect of this is a styled home page; however, all links off the main page to articles and menu selections within the site are not styled because the path to the CSS seems to be wrong due to the rewrites.

any ideas?
