Ok. I see.
On one side, doesn´t make sense, because if it wasn´t placed on the right folder, some translations shouldn´t work either, but anyway, I did as you said, but the result still the same. The same parts which were´nt updated on the frontend still unchanged!
There are translations which still unchanged when you change to EN and the same when you change to PT.
P.S. – some folders don´t have the .mo/.po files because I didn´t translate them, but I´m in the process.
