Re: Keymaster reset issue
Just run the upgrade (bb-admin/upgrade.php) – it doesn’t delete (or drop or truncate) anything, it just upgrades the database. You can view the source of the functions called by upgrade.php right here:
If you WANTED to reinstall, you would need to clear the old tables, then run install.php. Don’t do that.
And with any upgrade script, be sure to backup your database and filesystem first.
