No data for this graph for time report


I just updated to 1.8.3 fews few days ago.

Today i can see visit by time report for today but not for yesterday or one week ago or any other past day.

I’m keeping action 15 day in order to see these time report during 15 days. It works perfect before (v 1.5)

How can i solve this issue to get these reports (visit by time) again ?



please post a screeshot to show the problem as I don’t understand ? thanks!

Here is what i got.

There is no more available stats from visit by time before today.

only for this report, or are other reports also not showing data ?
