I got this warning in the PDF report generated.
And seems the graph cannot be generated.
How to get rid of this?
I'm seeing the same thing occur on my splunk server. splunk-4.1.7-95063.x86_64
Completely uninstall any old flash plugin and reinstall new flash.
The following worked for me in Ubuntu:
sudo apt-get remove --purge flashplugin
sudo add-apt-repository ppa:sevenmachines/flash && sudo apt-get update && sudo apt-get install flashplugin64-installer
