Fragment of a discussion from Support/LiquidThreads
Hi Calad-ne-dúath,
The language code: Sjn is actually not supported by translatewiki. We recently fixed a long standing bug where translators were allowed to translate to unsupported & invalid language codes. While sjn is valid, it is not supported by translatewiki.
I'm informing one of our staff who will review if support for this can be added to translatewiki.
Regards,
