Okay so here's my problem. I have a side bar on the left in my header.php file. In this side bar I would like to display the title and date of my most recent post, no matter what is being displayed in the body of the site. i.e. a "page", a post from years ago, even the most recent post itself.
I am new to editing the PHP of WordPress and all my attempts at this have failed. I have searched through the codex and found nothing that has worked so far.
Any help is appreciated!
