I love the Highwind theme, but I've had an issue with it for the past few days. I'm setting up a blog for work, and I added the widgets I wanted to the sidebar. It appeared on the right side of every page, as it should, until this morning. I've searched other threads on the forum and the best suggestion I could find was to check the "WordPress should correct invalidly nested XHTML automatically" box under Settings -> Writing. I did that, edited every post (there are only 3), and the sidebar is still showing up at the bottom.
