I just upgraded from 1.5 -> 2.5.1. Previously I had a page titled 'What's New'. The blog's front page contained my most recent posts. If the user clicked the 'What's New' header, (after say, clicking on a few other pages so they couldn't see the most recent posts anymore) they would be taken back to these recent posts.
Now that I have upgraded this does not work anymore. The front page still contains all the latest posts. But, when a user clicks on 'What's New' now, only my oldest post is displayed.
I have deactivated all plugins and reverted to the classic theme, so I don't think plugins or themes are my problem.
Under Settings -> Reading, I have specified the following:
Front Page Displays:
(checked) Your latest posts
(unchecked) A static page (see below)
Front Page: Overview
Posts Page: What's New
If I elect to check 'static page (see below)' I start to get confused. If I make both the front and posts pages equal I get warnings and weird behavior. Why? Why can't your front page also be the page where your posts show up? If instead I make the front page equal to Overview (as shown above) then visitors won't be able to see the most recent posts until they click on What's New.
