I've just installed a fresh copy for our testing environment and after importing vb3 and rebuilding the search index the admincp is empty. Please see the screenshot...
It doesn't look like you have any admin permissions. I'm guessing you were a super admin as defined in config.php before but you didn't migrate that across? You need to add your user ID to it (comma separated list).

That was it! Strange thing was only, that I've worked yesterday as admin just fine and imported everything without having my user-id added into the config.php. Now with my userid in it, everything works fine. I have to add that to my migration to do list
