I have just recently updated to WP3.0 and I just noticed today that my home page shows just fine (www.treewalkerdesigns.com) but when you click on any of the links there is an error message:
The requested URL /contact/ was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.”
This happens similarly on every page or category. When I look at my Dashboard everything is there, all of my pages, posts, plugins, etc.
Help Me Please Find My Site. BTW I am still pretty noobish with WP.
