Monitoring overview empty after upgrading fro, 4.4 to 5.0

[Polle]

Hi,

Just upgraded my Zabbix server running on CentOS 7 from 4.4 to 5.0. That went reasonably well after figuring out the rh-php72 stuff. All seems to be working well except for one thing: the Monitoring - Overview page is not showing anything although the Monitoring - Problems page shows like 60 problems with severity Warning or Average. Only when I select some host groups it shows me some triggers but even then it doesn't look correct at all (just a few instead of the 60 expected) - and when I select all host groups, it again shows no problems.
Any idea what could be wrong?

One more strange thing is that when I apply a filter and select a host group, some alarms are shown on the overview but not all the alarms for that group (the 'Problems' page shows quite a few more). If I select multiple host groups for the filter, I get again 'No data found' (depends a little on which groups I select but always at most a few problems - just a handful - is instead of a few dozen).
Anyone?

Using 5.2.4
Data Overview for us shows data for some hosts, but not others. I'm using a filter for Application.

When I also add a filter for a single host that is not showing data, then that one host shows the data just fine.

I'll see if I can report a bug on their other site.

I managed to fix my problem - turned out to be a version problem - I had a mix of RPMs from the release repo and from the test repo. Must have happened accidentally (certainly not intentionally).
