I guess the problem is that chi
is the bibliographic alias, you can use it for Config.language
, but the folder has to use the terminological name, which is zho
.
The terminological codes (first one per language) should be used if possible.
They are the ones building the path in/APP/Locale/[code]/
The bibliographic codes are aliases.
