Unfortunately I think that Translating CKAN page in the docs is quite out of date/just not very good. Still, if you have a ckan/i18n/*/LC_MESSAGES/ckan.mo
file in your CKAN source directory (where *
is the language code for your new language), and you have restarted your web server, the language should be available.
If it doesn't show up after restarting your web server, you could try setting locale_default in your config file to your new language and then restarting the web server again, and see if your language works as the default.
