I had created a group, added all users to it, and selected specific ones with “Admin” permission, so that they can add/remove users from this group.
However, still the message “” is shown and it is not possible to modify the group (roster) from Spark using any user (I can only add/remove from the administration page).
Is this caused because I’m using the embedded database (which is more limited?)? Any ideas?
Thanks in advance,
