I changed the permalink setting here: Log In ‹ Stay on Kelleys Island — WordPress under “Category (Listing)” to “properties” and the urls have not changed. I have cleared both site cache from a plugin and the actual site hosting and it has not changed.
Hi, please refresh the permalink structure in Settings/Permalinks (choose any structure with %postname% if the default one is selected) and check if this issue persists.
Also, please check that you filled in the field Listing, not Category (Listing).
