I only added this custom code to show product link in my order mail. Maybe that can affect your plugin ?
//Add img +link in woocommerce order mails
// Displayed by default, so hide!
function filter_woocommerce_order_item_name( $item_name, $item, $false ) {
// Only email notifications
if ( is_wc_endpoint_url() ) return $item_name;
$item_name = ”;
return $item_name;
}
add_filter( ‘woocommerce_order_item_name’, ‘filter_woocommerce_order_item_name’, 10, 3 );
// NEW OUTPUT
function action_woocommerce_order_item_meta_start( $item_id, $item, $order, $plain_text ) {
// Only email notifications
if ( is_wc_endpoint_url() ) return;
// Settings
$image_size = array( 64, 64 );
// Get product
$product = $item->get_product();
if ( is_object( $product ) ) {
$sku = $product->get_sku();
$image = $product->get_image( $image_size );
}
// OUTPUT
// Show image
echo ” . $image. ”;
// Product name + link + SKU (if set).
if ( $sku ) {
echo ‘‘ . $item->get_name() . ‘ (#’ . $sku . ‘)’ . ‘‘;
} else {
echo ‘‘ . $item->get_name() . ‘‘;
}
}
add_action( ‘woocommerce_order_item_meta_start’, ‘action_woocommerce_order_item_meta_start’, 10 , 4 );
