Reply To: Component image lightbox not working with Composite Products plugin

Try to add the following PHP code snippet to the child theme functions.php file to fix this

add_action( 'after_setup_theme', 'woodmart_add_wc_gallery_lightbox', 100 );

function woodmart_add_wc_gallery_lightbox() {
	add_theme_support( 'wc-product-gallery-lightbox' );
}
