In my WordPress 3.8 in my "Permalink Settings" I've chosen the option "Post name". Then I've added "Optional" for "Category" (
%category%/%postname% ), the URLs works like I wanted -
http://example.com/categoryname/postname - however this rule doesn’t apply to the editor - when I create new post or edit the existing post the URL in editor is still
http://example.com/postname, so when I click on View Post or Preview Changes it redirects me to this wrong URL which shows Page Not Found.
Any help/ideas? what am I doing wrong?
