WARNING: /core/Filechecks.php(153)

After updating to Matomo 5.03 following message is shown in “Alle Webseiten”:

WARNING: /core/Filechecks.php(153): Deprecated - trim(): Passing null to parameter #1 ($string) of type string is deprecated - Matomo 5.0.2 - Please report this message in the Matomo forums: … (please do a search first as it might have been reported already) (Module: CoreUpdater, Action: newVersionAvailable, In CLI mode: false)

Hi @bhenselmann
Thanks for reporting.
Could you add the PHP version you use in the GoitHub ticket? (I supposed it was 8.x).
I created a ticket in GitHub:

I am not sure the update worked well, as the displayed error indicates Matomo 5.0.2.

Matomo-Version: 5.0.3

MySQL-Version: 5.7.44-48

PHP-Version: 8.3.2
