I encountered the same problem and edited wp-includes/widgets.php line 141 from
$defaults = array(
‘name’ => sprintf(__(‘Sidebar %d’), $i ),
‘id’ => “sidebar-$i”,
‘before_widget’ => ‘<li id=”%1$s” class=”widget %2$s”>’,
‘after_widget’ => “\n”,
‘before_title’ => ‘<h2>’,
‘after_title’ => “</h2>\n”,
);

to

$defaults = array(
‘name’ => sprintf(__(‘Sidebar %d’), $i ),
‘id’ => “sidebar-$i”,
‘before_widget’ => ‘<li id=”%1$s” class=”widget %2$s”>’,
‘after_widget’ => “\n”,
‘before_title’ => ‘<h4>’,
‘after_title’ => “</h4>\n”,
);

Thank you very much, works like a charm!

WordPress loop looks beautiful.
