Hello. I am a very beginner user of WordPress and BuddyPress and I am asking for help. the topic has been discussed several times, but I still do not know how to do it. I want to change the names in the profile menu ( e.g “notifications” ) to a different name. There are many codes here but I do not know how to use them and where to add them. I also used “Loco Translate” but it did not work. Please help.
