Fix for broken Twenty Eleven update

Hi, I just left this same message over in the themes forum, but thought someone here might need this same info. This might help save your sanity!

I was using the Twenty eleven theme and updated on June 13th as required. Then all of a sudden some of my menu buttons and some in the sidebar wouldn’t respond at all! It took a couple of days to figure out (and a lot of headaches) and some help from MaAnna of BlogAid, but it turned out to be a plugin (that should have been my first guess, not my last!). It was WordPress SEO by Yoast! I turned that off and everything came back!

Now, we know that plugin is excellent and I’m sure he’s working on a fix, so I’ll be reactivating that again soon, but I thought this might help someone else that had some problems like me. Moral of the story: check your plugins FIRST!!
