For anyone with this problem who needs sidebars, remove or comment out the following code in sidebar.php
<?php if (!dynamic_sidebar('main-sidebar')) : ?>
<div class="widget-wrapper">
<div class="widget-title"><?php _e('In Archive', 'responsive'); ?></div>
<ul>
<?php wp_get_archives( array( 'type' => 'monthly' ) ); ?>
</ul>
</div><!-- end of .widget-wrapper -->
<?php endif; //end of main-sidebar ?>
This should fix the problem though archive shows if you don’t have another widget in there.
