Yes, that's because you set the password field to the literal password,
instead of calling password() to generate a password hash.

More to the point, you need to call the password() function with your
new password as the argument.

...Yup, just like that.

So it looks as though the original problem was indeed that the upgrade
left you with mismatched passwords. Glad to hear that everything's
working now that they're consistently set again.
For future reference, always remember that no MySQL password changes or
grants take effect until you either execute 'flush privileges' or
restart MySQL. So any time you're changing the MySQL password for root,
use two sessions; change the password in one, flush privileges, *then*
try to log in a second session *with the new password*, so that you can
verify it's working *while you still have a logged-in session*, just in
case you get it wrong and need to reset it.
(Losing your MySQL admin password is fixable. It can be reset without
loss of any data, but you need to know what you're doing. Best to avoid
the situation in the first place.)
