I have a pretty plain WordPress 3.3.1 install with the stock twentyeleven theme. I dragged and dropped (via Appearance/Widgets) the Calendar to the Showcase Sidebar and clicked the Save button.
I expected to see the calendar on the Showcase Sidebar but I don't see any change.
What am I missing?
Update: Actually, I can't see now even the Main Sidebar. I could swear I saw it working. And yes - I tried the 3 different "Default Layout" settings in Appearance/Theme Options.
Also, I am using a *child* theme of twenteyelven (style.css only)
