New Cacti install and getting nan graphs

[Mikeeo]

I can't figure it out, no poller errors, but graphs are empty

any Ideas?

I changed from rrdtool 1.2 to 1.0.50 with no change. I did the debug page and I see nan in the rrd file, but its for EVERY host and every rrd file.

I have to be doing something wrong.
