The Tuneup Plugin has been updated several times and is up to 0.4, so if you’re behind, you probably want to grab the latest version and reinstall. Log out of your admin panel (this step is important, as I found from personal experience…ahem…), drop in the latest version, and log back in.

I’ll echo Mark’s call for people to install this WP upgrade plus the plugin fix. I think I pointed out in my previous post the NONCE implementation that’s introduced. That makes it a key security upgrade, actually. Which is why I went ahead and upgraded despite the various minor bugs it introduced (ah, the joys and ironies of software development…)
