Install successful, but "Error drawing graph" on all graphs

I can’t see any errors in logs, and it seems to be able to discover hosts, but just not graph things. Am I missing a lib, or a path wrong or some such?

I think it was a polling issue, managed to get it fixed by screwing with the cron jobs, so make sure your cron setup is working if you see this error.

Hi,
How to solve this issue.this is also my problem.

Hello,

Are you seeing that for all graphs?

Can you post output of /opt/librenms/validate.php

also post output of “show rrd command” when you go onto a broken graph

Yes! all graphs.

Here is my /validate.php

./validate.php
