I duplicated the template to make the website multilingual, and I need to edit the new language template's files but I can't find them on the server! where can I find them?
all the language files of the frontend side template is located in the language folder.
for example if you have protostar template :
then these two you can find in the root/language folder.
If you have duplicated the template folder, please also make a copy of these two files in the same language folder.
Hope it will help.
