Problem with Syslog Plugin

[fata51]

Hi, I have a problem with Syslog plugin. None syslog messages are displayed!

Here is my config :

Cacti Version - 0.8.7a
Plugin Architecture - 1.4
Poller Type - Cactid v
Server Info - Linux 2.6.18-5-686
Web Server - Apache/2.2.3 (Debian) mod_python/3.2.10 Python/2.4.4 PHP/5.2.0-8+etch10 mod_perl/2.0.2 Perl/v5.8.8
PHP - 5.2.0-8+etch10
PHP Extensions - zip, xmlwriter, libxml, dom, xmlreader, xml, wddx, tokenizer, sysvshm, sysvsem, sysvmsg, session, SimpleXML, sockets, soap, SPL, shmop, standard, Reflection, posix, mime_magic, mbstring, json, iconv, hash, gettext, ftp, filter, exif, dba, date, ctype, calendar, bz2, bcmath, zlib, pcre, openssl, apache2handler, gd, mysql, mysqli, PDO, pdo_mysql, snmp

Plugins

• Update Checker (update - v0.4)
  Host Info (hostinfo - v0.2)
  Device Monitoring (monitor - v0.8.2)
  Network Tools (tools - v0.2)

  Configuration manager (configmanager - v0.75)
  Network Discovery (discovery - v0.8.3)
  Syslog Monitoring (syslog - v0.5.2)
  Global Plugin Settings (settings - v0.3)

I'm using syslog-ng and my database "syslog" (actually the table "syslog_incoming") is full of syslog messages. I edited the syslog config.php file :

$syslogdb_type = 'mysql';
$syslogdb_default = 'syslog';
$syslogdb_hostname = 'localhost';
$syslogdb_username = 'root';
$syslogdb_password = 'somepassword';

Nothing is displayed in Cacti. Did I forget something? Is there a bug or something?
