Hello,
I am sorry but it’s not possible by default. It requires additional customization in theme files. You can contact WP Kraken team if you need help with this because customization is out the scope of our support.
But you can edit /themes/xstore/woocommerce/archive-product.php file and change position of this line
< ?php do_action( ‘woocommerce_archive_description’ ); ?>
to show description below.
Make your changes in the child theme to prevent losing them after theme update http://xstore.helpscoutdocs.com/article/32-child-theme
Also read about After products widget area http://xstore.helpscoutdocs.com/article/48-widgets-custom-widget-areas.
