 * After the latest WooCommerce update I began seeing this message at the top of
   several of the pages in the WP Dashboard.
 * Warning: Missing argument 2 for wcpb_product_interface::wcpb_add_product_bundle_type()
   in /home/xxxxx/public_html/xxxxx.com/wp-content/plugins/wc-product-bundles/classes/
   admin-form.php on line 20
 * Using WP 4.5.2, WooCommerce 2.6.1, and WC Product Bundles 1.0.7

 * If you dare, do the following modifications until a new version is available.
   This will remove the warning message as well as fix a problem when adding product
   bundles to the shopping cart.
 * classes/admin-form.php – approx. on line 20
    look for: function wcpb_add_product_bundle_type(
   $ptypes, $ptype ) {
 * replace (just remove the 2nd var) with:
    function wcpb_add_product_bundle_type(
   $ptypes ) {
 * in classes/product-form.php – approx on line 143
 * look for:
    $added_to_cart[] = $product_id;
 * replace with:
    $added_to_cart[$product_id] = $quantity;
