Graph debug errors and graphs not displaying.

[brundle]

Under graph management for a graph with graph debug on I receive the following:

Warning: popen(d:/stats/rrdtool/rrdtool.exe graph - --imgformat=PNG --start=-86400 --title="Platinum - Traffic" --rigid --base=1000 --height=120 --width=500 --alt-autoscale-max --lower-limit=0 --vertical-label="bytes per second" DEF:a="d\:/inetpub/wwwroot/cacti/index.php/cacti/rra/platinum_traffic_in_23.rrd":traffic_in:AVERAGE DEF:b="d\:/inetpub/wwwroot/cacti/index.php/cacti/rra/platinum_traffic_in_23.rrd":traffic_out:AVERAGE AREA:a#00CF00:"Inbound" GPRINTLAST:" Current\:%8.2lf %s" GPRINTAVERAGE:"Average\:%8.2lf %s" GPRINTMAX:"Maximum\:%8.2lf %s\n" LINE1:b#002A97:"Outbound" GPRINTLAST:"Current\:%8.2lf %s" GPRINTAVERAGE:"Average\:%8.2lf %s" GPRINTMAX:"Maximum\:%8.2lf %s" 2>&1,rb) [function.popen]: No error in D:\Inetpub\wwwroot\cacti\include\rrd_functions.php on line 58

Warning: fgets(): supplied argument is not a valid stream resource in D:\Inetpub\wwwroot\cacti\include\rrd_functions.php on line 72


I was getting this under 0.68, and now still under 0.8. I am assuming this is the same reason no graphs display.

It looks like it is referencing an incorrect path - d/:\inetpub... although the path_webroot is correctly set.

Any ideas?
