Visitors not displayed in graphs after update to v3.0

After I upgraded our different Piwik-installations, the visitor count (as well as in the ecommerce overview) is not displayed in the graphs. But visitors are still logged by Piwik.

Anybody else has this problem? Any idea if there is a fix?

We haven’t heard of this issue. maybe open a ticket in our tracker: Issues · piwik/piwik · GitHub

We use PHP 5.6 on both servers (two different piwik installations).
