Unfortunately custom footer can’t be set for Shop page and product categories pages. On these pages footer from “Footer 1” and “Footer 2” area is loaded from Appearance > Widgets that is . Here is the tutorial how to create footer: http://8theme.com/demo/docs/woopress/#!/9_footer
You may open wp-content\themes\woopress\woocommerce\archive-product.php in text editor. Please add following code with block shortcode within instead of ‘shortcode’ in line 118 just after the closed </div> tag for sidebar. <?php echo do_shortcode('[shortcode]'); ?>
We strogly recommend to make all changes within the Child Theme.
