NC12.0.2 running ubuntu 16.04 latest patches in Dutch language/localization.
As I have some issues with the Dutch language at multiple sections I tried to change a few times the .js or .json file
However at settings directory or other ones like activity I change both the .js and .json file equally but I still see an error then like: Warning l10n Failed to load /var/www/html/nextcloud/settings/l10n/nl.json - json error code: 4
and when that happens all my e-mails changed to English language. Is there not any way I can change or type a few more words in the .js or .json files?
