Weird error in dashboard

[andresf]

This message appears today on zabbix UI Dashboard (Zabbix 3.2.4)

Last 20 issues

Undefined index: lastEvent [zabbix.php:21 → require_once() → ZBase->run() → ZBase->processRequest() → CView->getOutput() → include() → make_latest_issues() → make_popup_eventlist() in include/events.inc.php:441]

And then shows the current issues (as normal).

I didn´t touch anything.

Any advice should be helpful

Thank you Atsuchi!

I will give it a try. But can I only apply theese changes to my current 3.2.4 version, because the problem is in a production server and to change to anoteher version I need to do a testing on this new version before change it.

Can I emulate this error in a test environment? Can you give the minimal steps to reproduce it? (delete some record from table X ...)
