I have a new blog up at http://cookinghour.com and every internal link leads to a 404 error, including about us, contact, comments, etc. I'm using WP version 2.8.4. Some other posts here at the forum say it's a Permalinks issue. I changed the permalinks to my preferred type in the settings area. It's been over 12 hours since I did that. Any thoughts on how to fix this?
