No Graph data after upgrade

[tj333]

I upgraded from Ubuntu 10 to Ubuntu 18.04 and upgraded cacti to 1.1.38 along the way.

All of my devices and Weathermaps are there but I don't seem to get any data in any of them. I'm not sure what I missed. My error log looks like this:

You might want to check that all the "Settings > Paths" are correct.

[tj333]

What do I check them against to make sure they are correct?

It depends on your installation/distribution. You have to have green sign on all rows. Try to use locate or grep command:
locate spine | grep bin
which spine
...

Thanks for the help. Between that and changing my rrdtools version I seem to be working.
