I just updated to WooCommerce Version 3.1.1. Now the thumbnails on the products page are showing up full size. https://m-rockstone.solutions/shop/aspen-ledge-stone/
I tried to do a Regenerate Thumbnails, but that didn’t work. I also tried this that I found but it stacked the thumbnails:
add_action( ‘after_setup_theme’, ‘yourtheme_setup’ );
function yourtheme_setup() {
add_theme_support( ‘wc-product-gallery-zoom’ );
add_theme_support( ‘wc-product-gallery-lightbox’ );
add_theme_support( ‘wc-product-gallery-slider’ );
}
