Graph error

[scharpy]

Ok, I'm running Debian 3.1 and I've installed cacti 0.8.6c, Apache2, mysql-4.1, rrdtool 1.0.49, snmpd 5.1.2 and php4 through aptitude.
First I had a little issue that the poller couldn't make graphs. It was something wrong with the php-cli config, but I fixed that. And now when I run the poller I get this:

OK u:0.01 s:0.00 r:1.01
OK u:0.01 s:0.00 r:1.02
OK u:0.01 s:0.01 r:1.02
OK u:0.01 s:0.01 r:1.02
OK u:0.01 s:0.01 r:1.02

But now I got a new problem, I only run cacti default so it only monitors memory usage, users and such on the server untill I learn how cacti works and such. Like you see it have written a graph, but only a few times.
I've checked the log and it's ok there.

What's wrong?

Ok, I found out, if I run dpkg-reconfigure cacti, then enter the right values and after that restart apache2, it write a graph, then stops again.
Anyone know what's wrong?
