hi
i’ve got news…
and i think i am able to objectivate the problem.
go to https://kingshah.com/ and in the main search look for “Stoney”
you’ll obtain a lot of results and if you scroll down – in the “Other results” are the WP Categories and in Taxonmis the is nothing.
Other results they were not displyed because of “If result does not match any group? – Remove it”
So the objective problem is that main WP Categories fall into “not able to be grouped” amd Taxonomies generate no results.
If you still want to inspec the search you can see the “search homepage” in the admin area..
I keeped the same credentials for you…
