Since I updated from 3.8.1 to 3.9.1 (I skipped 3.9.0) the number of visitors are always equal to the number of page views (maybe the first one). This is a show stopping bug.

I think I cannot help you with this issue than.
It works again. I did the » Manual Three-Step Update« as described here: Update Piwik User Guide - Analytics Platform - Matomo
After finishing this, it seems that Matomo is correct working again.
