The clean story URLs do not work on my website

[kelp]

Here's what I've done to achieve clean URLS:
1. use the .htaccess that comes with the pligg installation
2. enable 2 on the url configurations

When I click on a story, it goes to a 404 error page. The clean URLS work for categories, though.

We need a link to the site.

I'll just use "dirty" URLs for now, so I can get some work done on my website. Maybe it will somehow work in the next version when I upgrade. Thanks, though.
