When you select the user setting area, you can see the comment like “In order to install another language , Go to Extension manager and install required language pack”
But seems to be its not working or specified backend language packs are not available…
Do the following steps to add German or any other language:
- Choose Extension Manager , then select Menu “Translation Handlling”
- select the desired language
- verify / update from Repository
Now you can see the new language in User settings language selection list, the backend language. Relogin and done!
