Please see video above / when an error is thrown it does not go to the 404 page, you either land on a listing page or as below.
https:// mysite . net /united-states/ < the url generated in a 404 error or the listing page, but not redirecting to the mitesite .com /404 page
Again happy to fix this myself if shown where / how
Thank you.
NB: This I think is connected to an even bigger problem / and involves googles indexing and links back to the site.
