[faceless]

Hi all
I have a problem with my cacti ..
I installed it couple days ago and since i`m no so familiar with it i have some problems that i could note solve by myself..
Cacti load the graph but does not show anything into it..
Just empty scale .. as the .jpg shows ..

The log file in /cacti/log ->

I experience the same problem.
You will notice the cacti log file was not being populated, probably the cron for poller.php is not running
try to create a cron for the user cactiuser.
It works for me.
