@TE the lang map in the config file should be updated to:
lang_map = en: english, de: german, pl: polish, it: italian, id: indonesian, de_DE: german-formal, es: spanish, ar: arabic, fr: french, nl: dutch, el: greek, pt: portuguese, es_419: spanish_latin, zh_CN: chinese, pt_BR: portuguese_brazilian, es_AR: spanish_argentina, hu: hungarian, th: thai
There are more actually, but these are the ones that appear on the site, so I guess for the time being that's enough.
