Why is there also a .CVS file which seems to have the same content as the .json file? Dana Anderson February 12, 2018 17:45 Updated Follow We provided both formats for ease of translation. You can delete the file that you don't use. Related articles I noticed there were files named xx.json and also xx-Xx.json. Can i just replace them both with the same content? Do i need to restart the service for the language files to be used after updating? Where are the language files located?
