Thank you! I found the culprit. It was the single Snippet I had running. Could you explain why this snippet would kill the Layered Nav functionality after the recent update?

function exclude_product_cat_children($wp_query) {
if ( isset ( $wp_query->query_vars['product_cat'] ) && $wp_query->is_main_query()) {
    $wp_query->set('tax_query', array(
                                    array (
                                        'taxonomy' => 'product_cat',
                                        'field' => 'slug',
                                        'terms' => $wp_query->query_vars['product_cat'],
                                        'include_children' => false
                                    )
                                 )
    );
  }
}
add_filter('pre_get_posts', 'exclude_product_cat_children');

I switched over to one of the free themes with no luck. I made sure the filter was listed in the URL when I tested it and it was.

i.e. http://www.bbqgrillpeople.com/product-category/grills/built-in-grills/?filter_manufacturer=blaze

Nuts 🙁 I deactivated the Advanced Ajax one in the plugins menu and still no-go. Filtering still just refreshes the page and continues to show all the products.

No, that’s the problem: when a user emails the cart containing an item with options, only the bare parent products is restored when they click the link. Any and all options that were selected are not restored.
