I'm having a weird problema with Twenty Twelve - when I go to the Widgets admin area (wp-admin/widgets.php) there's nowhere to move my widgets! And they do appear in the main page, in the sidebar.
I need to add a new widget (search) in the sidebar and I'm lost. My blog (in fact, my wife's blog) is http://www.anica.com.br
I put a printscreen here: http://www.anica.com.br/?attachment_id=5988
