Sorry I din’t explain myself properly. The issue with the plugin is that only states from US appear (so the coin is only $). I tried to desinstall and reinstall.
Thank you very much for your help. I did it but I think I didn’t right, I still see sentences as “keep me signed”, “forgot your password” or “register” in buttons. Maybe it’s not in these files where I have to translate forms words. Thank you again!
