SharePoint Server 2010.
User is member of the Site Owners group, however he is not able to modify group membership. He can grant permissions only directly.
As seen in the screenshot, the New menu is missing when opening the Group's membership.
A possible problem is that the Group owner field in Group Settings is incorrect. Maybe a legacy setting from SharePoint 2007 or a manually created SharePoint group.
Solution: Add the Owners group as the group owner.
In this case, if the site's name is Dashboard, add Dashboard Owners as the owner of all 3 site-related groups: Dashboard Visitors, Dashboard Members, Dashboard Owners.
You may need Site Collection or Farm admin rights to restore these permissions.
