When I try to present only a subset of services, employees or clients I should be using category slugs. Right?
Now when I enter a slug in the field: “Enter the slug for your category or leave empty to show all services.” the result is that there are no services (or employees or clients) at all on the page. The headline vanishes too.
I tested with different pagetypes but the results were consistent. I also deactivated all possible plugins. But I just can not get this to work as supposed.
So, what can I do?
