There are two Super Admins on this multisite. As one of them I can see the WPMU DEV dashboard in the sidebar menu at http://pci-learning.com/wp-admin/network/. However, the other Super Admin does not see it. We both have the following Membership Permissions:
Dashboard, Members, Levels, Subscriptions, Coupons, Purchases, Communications, URL Groups, Pings, Gateways, Options, Permissions, Superuser
The same is occurring on our other site http://www.performanceconsultants.com. This is a single site installation and we are both Administrators. Again, only I can see the WPMU DEV dashboard menu on this site.
