I'm using Wordpress 3.1.3, Atahualpa 3.6.7 and have installed all 3 bug fixes.
My home page shows fine but when I click on a link in my menu I get a 404 Not Found message. When I try to manually paste the permalink I still get the 404 message. It was all working fine before I did the upgrades of wp & ata.
What can I do?
