I originally got the Class fof40 container not found and followed the instructions on this post:
https://www.akeeba.com/support/admin-tools/Ticket/34670:class-fof40-container-container-not-found-2-2.html
After installing 6.0.2 twice I was able to open Admin Tools but only see: Emergency Offline, Master Password, Password-protect Administrator See attached screen shot.
I've tried uninstalling and reinstalling but get the same results.
