2.0.2 - graph data not showing

[bundaburg1]

Hi,
Ive just upgraded from 1.8.12 to 2.0.2.. everything is working well except for graph data. There is a blank where the graph is meant to go.

I have confirmed that within the last 500 values, there is data.

httpd logs show no errors, access log show none either:

x.x.x.x - - [12/Aug/2012:12:48:58 +1000] "POST /zabbix/jsrpc.php?output=json-rpc HTTP/1.1" 200 366 "http://xxx/zabbix/screens.php?sid=b5bf6005091c78c6&form_refresh=1&fu llscreen=0&elementid=6" "Mozilla/5.0 (Windows NT 5.2; rv:13.0) Gecko/20100101 Firefox/13.0.1"

Thank you!

Hi,
Has anyone else come across this issue?

Every graph does not work - the screen is complete except for the graph itself. 500 latest values appear without any problems?

Thanks!
