Hi, I’m using Matomo (Piwik) for some years now. Did not have many problems all those years. And if any, than I was able to resolve them. But now, after a update to the latest version of Matomo, I do not get any data from the sites monitored ? I have had a look at all settings, even installed a new download over my existing Matomo version. The Matomo is running on a Debian server. The system control does not have any error. The implemented tracking code seems ok to me. So I am out of ideas where to look at and find the problem.
Any idea how to solve this? What else can I try?
