If you mean the admins list on the top right of a group header, simply remove the appropriate function call who is in the /bp-default/groups/single/group-header.php file
Line 7 and above… or remove the complete div + content (admins and mods)
To do this properly, make this from within a child theme.
Hello thanks for your answer @danbp 🙂
Yes I have already deleted this line in group-header.php 🙂
Sorry if I was not clear enough, I was talking about the “members list” tab in the group itself 🙂
Read here exclude_admins_mods
Thank you @danbp I will try this! 🙂
