I just installed WordPress on a SUSE Linus Enterprise Server 10 system. At first it seemed everything was fine. I can change the theme and create posts. The problems I'm seeing are four-fold. I can preview a page while I'm creating it, but after I publish it and try to access it I get a 403 error. I created categories, but when I click on a category name on the main page I get a 404 error. When I click on the title of the post I get a 404 error. And when I try to comment on a post, I get a 404 error.
