how to fix the widget for the edu-clean theme?

after installing edu-clean theme, the front page has a side-bar with no widgets.

the message in the sidebar reads: Please log in and add widgets to this column.

and there is a “Add Widgets” link going to the widgets section. No matter how

many widgets I add nothing changes in the main page. widgets for other pages

(e.g. members) work. it is just the home page that doesn’t work. I was hoping to

add at least the blog-roll.
