servicewordpress on "[Plugin: WooCommerce - excelling eCommerce] Woocommerce - Display multiple pages for one category"

This is working for the root page of the shop, but not in my sub-pages of the shop.

Example:
Shop --> CATEGORY PAGE X --> PAGE X:

In this page, I add the shortcode :

[product_category category="nameofmycategory" per_page="20" columns="4" orderby="date" order="desc"]

I see the page, the products on it, but no pagination at the bottom.

thanks,
