[Archivesspace_Users_Group] Cannot add new user

[Hambleton, John S]

Folks, 

We just did our "production" migration to ArchivesSpace.
All the ArchivistsToolkit users migrated as expected. 
However, now in ArchivesSpace, I click System > Manage Users >
Create User > this takes me to the ArchivesSpace home page...
We're version 1.0.9, used the latest migration tool.
I have administrator privileges. And this malady even happens
with the "Admin" account...

Possible causes? Work arounds?
Many thanks,
