After updating to Openfire, Version: 3.9.1 administrator password stopped to work

Today, I have updated Openfire to Version: 3.9.1

Administrator password I have set during installation procedure does not work.

I have restarted service after set up process using command:

/etc/init.d/openfire restart

I have tried to restore encryptedPassword from previous version 3.8.2 SQL backup, restarted OpenFire service using

/etc/init.d/openfire restart

But it does no work too.

I have tried to reset it by setting plainPassword = 123456 and encryptedPassword = NULL for username = ‘admin’, restarted openfire service using command

/etc/init.d/openfire restart

Do I have any chanse to fix this issue, or should I downgrade OpenFire to previous working copy from backup I have?

Same problem here.
