PSA http 500 error after upgrading to 11 from 10

[Ernie@]

Can't access to the Panel after upgraded to version 11.

Ran bootstrapper repair, it suggests to update the password format for the following accounts


Tried bootstrapper.sh repair, it says,
------------------------
***** problem report *****
Passwords for some MySQL users were not upgraded.
All MySQL DB users that may be used by Panel MUST have passwords in new 41-character format in order for Panel to function properly.
Currently following users have passwords in old format: billing@localhost, aspcomplete@%, aspcomplete@localhost, aspcsk@%, aspcsk@localhost, aspcss@%, aspcss@localhost, aspsession@%, aspsession@localhost.
Please ensure that MySQL server is not forced to use old password hashing algorithm and upgrade password format manually for users from the list above. Consult with MySQL server manual on detailed steps.
You may skip certain users if you are sure they weren't created and aren't used by Panel.

Any idea?

Thanks.
