Yesterday I upgraded to the latest version of WordPress, and didn’t do a very good job of it. Because I forgot to upload one key file, the appearance of the blog has been off-kilter for 24 hours. If things still look hinky in your Web browser, try reloading this page, and if that doesn’t work (Safari users, you know who you are), empty your browser’s cache (e.g., go to the “Safari” menu, select “Empty cache”).
