WordPress newbie in a problem

Hello;

I’ve run into a snag in putting up a new blog.
I’m Hosted at ixwebhosting.com, at bitsblog.florack.us

THe issue is that the links don’t work at well, if at all. Look at

http://bitsblog.florack.us/index.php

Note that the comments links (as one example) answer with:

Directory Listing Denied
This Virtual Directory does not allow contents to be listed.

Anyone have an idea how I might get around this one?
