Thank you, but I have tried that before and does not work neither. At least for me.
I have cleared the cache, of course.

Yes. I have tried Loco Translate too, but there must be a problem with the strings because Loco plugin does not find the words I need to translate: Accept, Decline, Print. Perhaps they are defined in a javascript file?
Basically Loco Translate do the same that Poedit, although in a easier way. It takes the .mo/.po files and export the language translation.

Please, could you help me?

Thanks!
Best Regards.
