I want to add a language to the display languages so that the
admin interface can be translated.
I have added a language, I have uploaded and imported the language, but it is not showing in the
Display language drop down.
I can export all the translations from the top node in the
Content Editor, and I see the language I added, but not some of the languages in the
Display language list.
How do I get my new language added to that list?
