Since upgrading from 2.0.5, when I'm in admin under Manage|Posts, the search functions on this page do not work. They return a "404 Not Found" error. ALL OTHER search functions throughout the site work fine.
This occurs on 2 different blogs, BUT...it is working fine on a local copy I run from a thumb drive on which I first test all upgrades.
Can someone clue me in as to where to begin looking, or perhaps identify which files I might try reloading? Any help would be MUCH appreciated. Thanks.
