[cacti-user] Thumbnail and graph not showing

I am using rrdtool-1.2.16, cacti-0.8.6j, net-anmp-5.4 and php-5.2.0.
All the thumbnails are broken and some of the graph are showing
alright and many are not showing at all. When I turned on debugging,
it show unknown controll code ERROR as shown below. Any idea how to
fix this error?

Thanks
