Using taxonomy translation, we have translated existing custom taxonomies to the fr-fr and it-it languages.
The current scenario is, for example, that we have one taxonomy named demo for en-us, demo-fr-fr for fr-fr, and demo-it-it for it-it.
The issue is that when we try to open archive pages for demo-fr-fr and demo-it-it, it gives me a 404 error, but it works for demo perfectly.
