I'm trying the Mystique Skin and all works well but the Tabbed Widget to the right is not showing Archives, could anyone help me with that?

Could the problem be how the archives are called here?

{
		if( ! $this->get_setting( 'tabbed_widget' ) ) return;
		
		?>
        <!-- tabbed content -->
        <li class="block">
          <div class="block-sidebar_tabs">
            <div class="tabbed-content sidebar-tabs clearfix" id="instance-sidebartabswidget">
              <ul class="box-tabs clearfix">
