No category sorting to be selected

I think the plugin is working with WP 4.5 (April 2016) though it has not been updated for 2 years.

But what I need it for is not working, not available: sort by category. There is no field in the backend to switch from sorting by date to sorting by category.

I guess it requires programming abilities, which I do not expect from a plugin. I am not a programmer and like to use WordPress′ CMS.

Have to go on searching for another plugin that sorts by category… (weird enough to me that is not in the theme or WP in general as I would think it is useful for everyone in general).
