PDF Export (No Data for this Report) - works online!

Hi,
I’m looking forward to set up a weekly pdf export via mail.

If I press “Send report now” I receive an e-mail with a pdf file.
But the Data is empty.

But if I press Download PDF in Piwik I see all data that I selected.

How can I fix this?

I’m stupid…
It works fine. The Download button generates a pdf with the latetest data.
But the weekly PDF Export generates a pdf of the last week.

I installed piwik the day before yesterday. There is not data of the last week.

Problem solved ^^
