WordPress Super Admin menu not enabled

Newer versions of WordPress have gotten rid of the “Super Admin” menu on the left-hand dashboard menu in favor of a “Network Admin” section.

It sounds like you installed multisite just fine, so under the “My Sites” option in the top toolbar, you’ll now see a link to the Network Admin section.
