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).
