I think you are signed on as a user who is not in the system anymore, right?
Can you sign out or clear cookies or something and sign in as a user who
exists and do another invite?

Subject: [grouper-users] External user invitations no longer working

I was doing some testing of external user invitations. At one point I
sent an invitation to an external account that was already registered
with Grouper. Then, in response to the invitation I clicked on the
delete button to delete that user's association with Grouper. My intent
was to reset that account as far as Grouper was concerned, so I could do
a test as if that account had never been used with Grouper. After that,
no external invitations are working, either to that user again, or to
other external users that had never been used previously with Grouper.
When I follow the link to accept an invitation, instead of getting the
screen for that, I get a "subject not found error". Here's the trace
from the log:

I never used the "delete" button in an invitation before, so I suspect
that has something to do with this. This seems very odd to me, because I
wouldn't expect the subject to be found before the invitation had been
accepted. Any ideas on how I can get it working again? This is not a
production system, so it's not urgent.
