Thanks for the fast reply, moshu!
The code I posted is the default sidebar.php that comes with the theme. If that li is a mistake, it’s done by the author. Using my very limited coder skills, ( but still enough to identify the blogroll part of the code) i found an extra /li too, so i ended up deleting this part, hoping the widgets might work.
</li>
</ul>
<ul>
<li>
Nothing happened, the behavior is the same.
