Hi @franckwylliams27, 🙂
Thank you for reaching out to us.
To change this text we really suggest to use the Loco Translate plugin, just as you already did:
Loco Translate
Once installed, go to Dashboard > Loco translate > Plugins > Grimlock for BuddyPress. The first time, perhaps you’ll have to create a new language. In your case, select the language of your website. Then, search the word you want to change.
If you don’t find this string, I suggest you click on “Synchronize”. It will automatically add the new strings.
We’re waiting for your feedback. 🙂
Wish you a happy new year. 🍾
Cheers,
