I've been searching the forums and have seen some references to similar situations, but mine is a bit different.
On an existing wpmu install I have an admin user named user1234. This was a fresh install with only the example posts.
On a standard wp install, I exported 1300 posts, pages, etc. I then imported this into the wpmu install. During import I was prompted to "attach these posts to user1234?" which I did.
Everything seems to be fine with the exception of the plugins and admin panel missing.
After some searching/reading/looking through the db, I simply went into the db and changed the username back to admin instead of user1234. This brought back the site admin and plugins panels in the dashboard...but of course I don't want the username of admin for security.
Does anyone have any idea on what might be the missing piece here? What did I miss?
