Description

I used Event correlation in ZABBIX for the verification work
I moved to the Dashboard, after confirming the operation of Monitoring Problems.
The attached image was displayed.

I edited the following and confirmed that the problem improved.
/usr/share/zabbix/app/views/monitoring.widget.problems.view.php
l.849

before
array_key_exists($problem['correlationid'], $data['correlations'])

after
TRUE == isset($data['correlations']) &&array_key_exists($problem['correlationid'], $data['correlations'])
