I just thought I’d document a problem I ran across 3 times today when I upgraded three of my WordPress blogs to the newest version (2.2.2). Suddenly, my themes looked all out of whack, with the sidebars having issues. Sections weren’t in the correct spots, and things I hadn’t had in my sidebar for a long time were there again. Turns out, it was an issue with old widgets suddenly reappearing and causing havoc with the sidebars which no longer use widgets. The solution was to install and activate the Disable WordPress Widgets plugin. Problem was solved immediately. Now, I’m not sure what any future consequences this may have, but for the moment, I’m happy. Thought some of you might need the info too.
