Is anyone have same problem? I fixed already. Just go to Appearance –> Editor –> content-product.php and replace
$placeholder_width = $woocommerce->get_image_size( ‘shop_catalog_image_width’ );
$placeholder_height = $woocommerce->get_image_size( ‘shop_catalog_image_height’ );
with
// $placeholder_width = $woocommerce->get_image_size( ‘shop_catalog_image_width’ );
// $placeholder_height = $woocommerce->get_image_size( ‘shop_catalog_image_height’ );
Works for me.
