Search Engine friendly URLs just wont work for me. All the pages give a 404 error whenever I enable it. The .htaccess file was generated properly by WP; I've checked to make sure. Mod rewrite is enabled and Joomla (which runs on the same url) has no issues with its own SEF urls. I'm not sure why it won't work.
Plus, clicking on any 2009 archive (ie. Jan 2009), gives the same 404 error.
Really odd.
