Hi @bigoslesli,
The updates in WooCommerce 3.0 will require to add a bit of code to you child theme’s functions.php file. Checkout the support tickets for Woocommerce. E.g: https://wordpress.org/support/topic/product-image-lightbox-not-working-in-version-3-0/
function catchkathmandu_child_woocommerce_support() {
add_theme_support( 'wc-product-gallery-zoom' );
add_theme_support( 'wc-product-gallery-lightbox' );
add_theme_support( 'wc-product-gallery-slider' );
}
add_action( 'after_setup_theme', 'catchkathmandu_child_woocommerce_support' );
Let me know how it goes. If this works out, we will add it in next version upgrade.
Regards,
Pratik
