Hello Folks. Good day. On my setup, I want the end users to change their email password directly on the Roundcube Interface. In order to do that, I enabled the "password" plugin on the /etc/roundcube/config.inc.php Code: // List of active plugins (in plugins/ directory) // Debian: install roundcube-plugins first to have any $config['plugins'] = array('password' ); After changing that line, the "Password" option shows up on the Settings menu on the Roundcube interface. However, when I try to change the account password by that interface, I get the error message: Could not save new Password Looking at the /var/log/roundcube/errors.log I see this Code: [19-Dec-2021 16:10:49 -0300]: <lip14rfa> DB Error:  FUNCTION roundcube.update_passwd does not exist (SQL Query: SELECT update_passwd('$1$Fkw1pWwF$rFbAjhqE2XkTVe1', '[email protected]')) in /usr/share/roundcube/program/lib/Roundcube/rcube_db.php on line 544 (POST /webmail/?_task=settings&_action=plugin.password-save) I'm not sure how to proceed in order to fix this error. I appreciate if somebody can suggest a correction for it. Thank you.
