I've just upgraded my blog from 2.0.4 to 2.1.
Now all my links such as excerpt link, archives and categories on the top page are no longer active and you can not see any pages any more. If you click one of these links, it shows my server's message "404 not found". I can see there are all posts in the admin panel though. I'm using the default theme for 2.1.
Anyone know about this cause???
Thank you for your time!
