[cacti-user] poller.php not running

Hi!

cacti poller is not running.
Starting it manually gives error message:

# /usr/share/cacti/site/poller.php

Warning: chdir(): No such file or directory (errno 2) in
/usr/share/cacti/site/poller.php on line 90

What could be wrong here?
As result i don't get any graphs in www frontend.
