I am a newbie to wordpress. I administer a blog which has a specific category, say Hidden, that is not shown in the recent posts lists. I do that using query_posts. The issue that I am running into is with published posts. Say, post 1 is published under category - General. Now I am come back and update its category to General and Hidden category. The problem is the post is still visible on HOME even if its category has been updated to Hidden. I am guessing that one of its revisions with category General is showing up. How can I update the revision.
