Non well formed numeric value - error message


In Invalidate reports, the following error message appears. Please advise.

WARNING: /var/www/clients/client0/web1/web/core/Piwik.php(138): Notice - A non well formed numeric value encountered - Matomo 3.13.4 - Please report this message in the Matomo forums: (please do a search first as it might have been reported already) (Module: CustomReports, Action: getCustomReport, In CLI mode: false)

I’m getting the same error, just have set up the custom reports plugin

Hi Clue,

Did this just happen after an update or installation of a plugin?


It was after an update, as I remember

Do you have a Solution for this?
