Some WordPress plugin update broke K2!

I just updated 2 plugins to their latest version on 2 of my websites – this one and Enhancing Clarity. When I went back to check them later, I saw, to my horror, that they were no longer centered on the screen.

Despite deactivating both plugins, the problem refused to go away so I had to tweak my themed style sheet with the advice I found here.

And it worked!! Hurrah!!
