The way that the Whitelisting works is that when you first import a Data Input Method, or you re-import a Data Input Method, and the script and or arguments change in any way, the Data Input Method, and all the corresponding Data Sources will be immediatly disabled until the administrator validates that the Data Input Method is valid.
Therefore, several versions ago, Cacti was enhanced to provide Whitelist capabilities on the these types of Data Input Methods.Though this does secure Cacti more thouroughly, it does increase the amount of work required by the Cacti administrator to import and manage Templates and Packages.
If SELinux is enabled on your server, you can either permenaanently disable this, or temporarily disable it and then add the appropriate permissions using the SELinux command-line tools.
