Old graphs work but new graphs don't

[PeteLettin]

Everytime I create a new graph the rrd file is not created and even if I manually create it by copying the command from the web debug the poller does not seem to add any data.

I get nan on the graphs.

The other graphs are still working.

The prime suspect is a plug-in I added recently but how do i fix it?

Looks like permissions of rrd files are set to root instead of cacti user apache2 runs as.

Cleared poller cache and chmod'ed files and things are working sweet again.
