I have almost everything working but I think I narrowed down my 2 issues to something with the RRD files.

When I try to run the realtime plugin, some graphs wont do it and give this error.
Some graphs on devices work and some dont, its not tied to the same graph template either. I checked the directory and the permissions are correct and it puts a png in there of the below error, also the graphs that do work there is an rrd file in there for it.

Error in cacti.log

The other issue when I click on the button (colored hamburger stack) to see the Time Graph View. That page just loads blank where the graphs should be. Other graphs will load fine.

Is there something else that needs to be done with that large of an upgrade path?

I speculate its an issue with timesteps/ or Data Source Profile RRAs now.

Thanks for any suggestions.

You really have installed realtime plugin? Can you see realtime in Configuration->plugins?
If yes, please disable and deinstall it.
Realtime is part of cacti many years.

No its not installed, not in the plugins directory nor does it show up in the plugins page in the Cacti interface. It was installed prior to the upgrade however.

show ls -al /usr/share/cacti/cache

are you trying run realtime for functional graph or for graph with error from your screenshot?
