I recently was playing around with the new Site Network function in Wordpress 3. For those who don't know what it is, it's basically the integrated WPMU in the new WP3 where you can run multiple wordpress sites off one installation. I am planning to use it to build a big website - it will definitely help make it easy to silo the posts.
Well as it turns out I f***ed up while I was fiddling around, and I had to revert from a backup. Now when I try to save some setting that I change in the dashboard, I get a "page not found" message. Any clues why this could be happening?
