After the 3.11 update
WARNING: /opt/html/piwik/plugins/Cohorts/Visualizations/Cohorts.php(96): Notice - A non well formed numeric value encountered - Matomo 3.11.0
Hi @a.laevskiy, could you tell me which periods and metrics you were viewing in the Cohorts visualization? And what version of Cohorts?
I’m able to reproduce this. I’ll post a response when this is fixed.
@a.laevskiy this should be fixed in version 3.0.5.
