No new graph data after update to 1.2.15

[mdknaebel]

Hello, I updated cacti via yum (centos 7) today (1.1.38 to 1.2.15). During the upgrade wizard I received a 500 error due to my PHP timeout being set to 30s. I resolved that and the upgrade appeared successful, but I'm not seeing any new data in graphs. Realtime graphing DOES work.

cacti.log is FULL (~128/second) of the following, repeated, since the upgrade completed:

Code: Select all

2021/02/19 17:01:19 - CMDPHP PHP ERROR WARNING Backtrace: (/graph_xport.php[118]:CactiErrorHandler())
2021/02/19 17:01:19 - ERROR PHP WARNING: Illegal string offset 'meta' in file: /usr/share/cacti/graph_xport.php on line: 118
2021/02/19 17:01:19 - CMDPHP PHP ERROR WARNING Backtrace: (/graph_xport.php[95]:CactiErrorHandler())
2021/02/19 17:01:19 - ERROR PHP WARNING: Illegal string offset 'meta' in file: /usr/share/cacti/graph_xport.php on line: 95

But I cannot find anything related to this error elsewhere. If anyone has an suggestions I'd be greatly appreciative.

I backed up my database and cacti directories and ran yum reinstall cacti. After moving files back into place, and fixing cron and file permissions, the issue appears resolved: Graphs are updating and I no longer receive that log message.

Not sure if this indicates any sort of bug, but it is now resolved for me.
