[Plugin: Simple Pagination] Need Help with Pagination for Defined Product Category

I’m sure its not the plug in but my lack of techy stuff. Great plugin and it works on my regular product pages but I have a side widget, the first widget of product categories and the first page is fine but all other pages give an error. Not sure what code or call or function I need to make it work. Any help is greatly appreciated. site: https://www.virtualstarr dot com
