Try this:

The MySQL fellas have made changes to how they hash their passwords. So, the driver used by mantis no longer works with the latest MySQL installation.

Somebody help.

actually you don't need to upgrade, just tell it to use the old password encryption like this:

SET PASSWORD FOR
'mantis_usr'@'localhost' = OLD_PASSWORD('qweasd');
