Eva,
I followed your instructions, yet am still having empty shop categories & subcategories. I reverted the theme to 3.6, upon doing so, the 3 images that linked to the categories (and their corresponding pages) appeared in the bulleted list rather than grid view.
Upon updating the theme to 3.7, the products disappeared. At this point I’ve reset it to 3.6 with the 3 SHOP page images appearing but not linking to the products.
*NOTE* The products are held in the “EMPTY CART” PRODUCTS found here: http://www.smokeybar.co.uk/wp-admin/edit.php?post_type=product NOT the “FULL CART” PRODUCTS listed here: http://www.smokeybar.co.uk/wp-admin/edit.php?post_type=wpsc-product (I’m unsure why there are 2 PRODUCTS sections in the dashboard navigation.
Can we try getting the products fixed before attempting to upgrade to 3.7 again please.
