phpWiki Preferences Error

[iascadmin]

The Plesk Application Vault version of phpWiki seems to fail in a variety of ways. I do now have it up and running, but when I try to change the preferences for the admin user, I get the following

Fatal error: Undefined class name '_peardbpassuser' in /home/httpd/vhosts/teleinteractive.net/subdomains/msi/httpdocs/phpwiki/lib/WikiUserNew.php on line 1101

which is contained in the following...

    function setPreferences($prefs, $id_only=false) {
        if (!empty($this->_prefs->_method)) {
            if ($this->_prefs->_method == 'ADODB') {
                _AdoDbPassUser::_AdoDbPassUser($this->_userid,$prefs);
                return _AdoDbPassUser::setPreferences($prefs, $id_only);
            }
            elseif ($this->_prefs->_method == 'SQL') {
                _PearDbPassUser::_PearDbPassUser($this->_userid, $prefs);
                return _PearDbPassUser::setPreferences($prefs, $id_only);
            }
        }
        if (_AnonUser::setPreferences($prefs, $id_only)) {
            // Encode only the _prefs array of the UserPreference object
            if ($this->_HomePagehandle and !$id_only) {
                $this->_HomePagehandle->set('pref', $this->_prefs->store());
            }
        }
        return;
    }

Is anyone using the Plesk Application Vault phpWiki successfully? Any ideas on this error?

Thanks in advance.
