After upgrading Icingaweb2 from 2.7 to 2.8 I have run into a weird problem.
I upgraded php to 7.3 as specified in https://icinga.com/docs/icingaweb2/latest/doc/80-Upgrading/
And after some issues (had missed the php module for Director for example) I got Icingaweb2 to work and could log in.
But now I have a weird problem. If i go to the history tab and check Event Grid / Event Overview I can’t see any history. If I go to a separate host/service I can see the history there.
If i check the notification history I can see it without any issue.
If I check the History Timeline I can see the “Hotspots” but if I click them there is no info.
Does anyone have any idea what could be the problem.
Best regards / Jens
