Session to become invalid

Hello people

I’am using UrBackup here and thing great!
But now, I just need create an account called auditor.
I can set grant to this user, like this:

browse_backups
lastacts
logs
piegraph
progress
status

But, when I logged in, see any client at all!
How can set to the unprivileged user auditor, see the one client I have backed up?!?

Thanks

Ok! I managed to set to see the options, but now, when I click in Statistics, I received the message:

Inactivity caused this session to become invalid.

Here the permissions:
