When creating a graph, undefined function prevents confirmation from appearing

[stormonts]

With Cacti 1.2.1 and 1.2.2, I am seeing an error in the logs and not seeing a confirmation window when I create a new graph via Create-> New Graphs. The graph is created, however if I place a check box in multiple boxes to create multiple graphs, only the very first checked graph is created.

The error in the logs is:

2019/02/25 10:36:43 - CMDPHP PHP ERROR Backtrace: (CactiShutdownHandler())

To reproduce, I go to Create, then New Graphs, check a box next to a graph, click Create. It doesn't matter what type of graph I select or which device I pick.

This is running on CentOS 6.10.

This was supposedly rectified in issue #2145 so it's curious that you seem to have it again.

Let me know what more you need from me.

Found it. The stack trace showed it all. Thanks!
