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

I have the same problem here. Worked fine in 2 but not in 3.0.
I use PHP 7.1 - maybe this is the same for you?

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

make sure to create a bug report with screenshot etc. in our tracker
