I've just downloaded the latest release of, and logged in as the default 'admin' user.

I was wanting to remove some of the displayed widgets by selecting and removing them from the Custom menu, but the "no-entry" icon is displayed when I try to click on their check box. I've noticed that the same thing also happens with the extensions and themes sections.

Would you know why I can't select these items?
