Nothing to display message when products should display

The Search and Filter plugin looks to be just what I need to display my Woocommerce (Version 2.4.6) products using Storefront theme with Storefront child theme.

Here is the code I used :
‘[searchandfilter fields=”search,product_cat” post_type=”product” headings=”,categories” types=”,checkbox” submit_label=”Select A Category” hierarchical=”,1″]’

I can see the categories display in hierarchical view. When I select a category and ‘click the select a category button’ I get the message ‘Woops that page cannot be found’. I know there are products in the category I select.

What am I not understanding here?

It seems like the results of my category submission is getting lost. What should I be doing?

I was really hoping to use this plugin.

Thanks for some direction.
