Hi @aumweb,
1) Can you tell us on which screen the button is displayed. Can you please provide us with screenshots? Please don’t hesitate to comment or highlight your screenshots to help us better understand what you’re looking to translate.
2) If you have the latest version of BuddyPress and its translation, it should work fine. Can you please confirm us that the rest of your BuddyPress pages are correctly translated to your native language?
Best regards,
