hmail plugin issues

[TechMonster]

Trying to use hmail_password and hmail_autoresponder plugins. They were working fine at one point. When trying to use hmail_password plugin it does not error for the user but the logs has the following error. It will not change the password. This is the similar dsn string as roundcube uses to talk to it's db. Please help.

Error

You'd probably get a better response asking the My RoundCube team directory.
