I am trying to install concrete5 to a godaddy shared hosting account. Since my account hosts multiple websites, I need to install it to a subdirectory.

The subdirectory is called "dev". The "Install concrete5" page loads and renders correctly, but when I click "Continue to Installation" none of the javascript or css loads. Inspecting the page source reveals that concrete5 is attempting to load everything from /dev/path/to/file.js instead of /path/to/file.js. All of these files fail to load of course.

I think I need to modify my .htaccess file or something like that, but so far I haven't been successful. What am I doing wrong?

The URL:
http://dev.thejusticeproject.net/...
