RoudCube password plugin not working

Hi,

I need help with the Password plugin to RoudCube.

I can't change password:
when I would change the password I get
SERVER ERROR!
Error No. [600]

When I rename the config.inc.php.dist to config.inc.php I get error:
Could not save new password.

config.inc.php file:
https://pastecode.io/s/i5g4aa83

How can I resolve the problem?

I use:
Debian GNU/Linux 12 x86_64(Py3.12.3)
OpenLiteSpeed
MariaDB

Hello, it is recommended that you make modifications from the mail server

Unfortunately, but I have many users who want to fully manage their mailboxes. I need the plugin to work. I believe there is any solution.
