When I tried to log in I got
the message "You may need to upgrade your course tables. If this is the admin course then you will need to upgrade the admin tables using the upgrade_admin_db.pl script."
So I ran the latter. There were a number of warnings saying that WebWork::DB::Schema:NewSQL:(Various):DESTROY was an undefined subroutine.
I am getting very similar messages when I try to change my admin password from the command line, and I can't remember the old one. I assume the problem is still with the database format? Any thoughts appreciated. Thanks.
