Cacti graphs not showing any values

[shlelieveld]

Hello all,

I just installed my new replacement server with the latest version of Cacti (1.1.6) to replace our old corrupted 0.8.8 to 1.0.4 crashed upgraded server.

I managed to get the package installed, and added my first switch to start testing all functionality. The graphs have been created (at least the first 2 for test) but the values remain -nan
and show nothing...

see screenshot...

Check cacti log, and rrdfile permissions.
