Hi Venutius, Thanks for your help. Incredible, the issue came from “BuddyPress Multi Network Plugin Network” 🙂 himself. I desactivated it, and I can now create new Groups. I just hope than new Register Users for this “MU-blog” on my Network don’t be mixed with my others MU-Blogs subscribers.
But nouw, I got a new problem : connected as Super-Admin, I create a group, but I forgot to choose a Cover-Group banner ; image, and I don’t see button or link to choose or upload a new-one.
Any idea ?
Thanks a lot for your time. Best regards 🙂
