 Description   

When clicking through the host graphs /graphs.php?context=host&page=4 it goes to a blank page. Looking at the php logs we get:

I believe this is due to graphs referring to objects which have been removed as this zabbix instance has been upgraded multiple times.

I am unsure where this is up to, but this patch I came up with fixed the issue for me:

    else if (!array_key_exists('ts_delete', $data['graphs'][$graphid]['graphDiscovery']))

    { $data['graphs'][$graphid]['graphDiscovery']['ts_delete'] = $ts_delete; }
