Looks like it working to me…
This page shows all entries:
This page shows all that are category “A”:
And this shows all “Acton”:
If you put the category widget shortcode back on the page (that was removed), above the
[connections] shortcode you will see the category links again. Clicking the link should filter by the category clicked.
NOTE: If you are going to use the links from the widget, you should disable the category filter feature in the template.
Hope that helps!
