Hey guys.
A little help with this will be very appreciated. Im working on a site for a client and currently there's only two users . The super admin and a test user. So i wanted to update some plugins and head over to the dashboard section , am currently seeing 4 sub menus under WPMUDEV which are 1.dashboard. 2:support. 3: community 4:manage. And when i try to update a plugin it says i do not have priveledges etc..

Thanks in advanced for any way in helping figuring this out. I have already granted support access.
