I've searched in the archives, but can't seem to figure out how this problem might be desccribed by someone else.
I'm having problems previewing pages.
For example, when I'm in the dashboard and I make a change, as soon as I click on "view site" it takes me to a directory of the site, "Index of /wordpress." If I add "index.php" to the url, then the page loads correctly with my changes. But I keep getting dumped into my directory (which I haven't locked out of public viewing yet while I'm still developing) rather than the pages that are supposed to load, like links to categories and month archives.
You can view this anomaly here:
http://www.dominantparadigm.com/wordpress/index.php
Click on one of the categories or load the URL without the /index.php and you'll see what I mean.
Thanks in advance for any help you can offer on this. I'm sure the solution isn't that complicated and evinces my ignorance about the way that php works.
