Hi there,
Currently we have only English (Great britain) file. To translate into German language, you need to do the following:
Copy the file from this location:
/administrator/language/en-GB/en-GB.plg_system_conversekit.ini
Paste inside here (I suppose you have German language installed, otherwise you will not find this folder thus you need to install the language from Joomla backend first):
/administrator/language/de-DE/
Rename the file pasted from :
en-GB.plg_system_conversekit.ini
into this:
de-DE.plg_system_conversekit.ini
Finally, go to backend, Extensions -> language(s), set German as default by clicking on the star under default option.
Do let me know if anything confusing. I would do my best to explain it.
Thank you.
