I dont know if you have found the solution ot this yet, but this works.

Change the write permissions to your rrd.log file.

chmod 777 ./log/rrd.log

If your rrd.log file wasn't writeable you wouldn't get any graphs. And when you run cmd.php it tells you " error writing file".

Leaper - Check for my post on this fix:

I downgraded to 0.8 and it worked fine. Then I upgraded to 0.8.2 and it worked.

Most often the problem is related to permissions of the user running your cmd.php. That user needs to be able to write to the <cacti_path>/log directory and the <cacti_path>/rra directory.

Also make sure that your crontab is actually running.
