I got the following warning after login to web interface.
WARNING: /var/www/html/piwik/libs/HTML/QuickForm2/Rule/Compare.php(103): Deprecated - Function create_function() is deprecated - Matomo 3.7.0 - Please report this message in the Matomo forums: https://forum.matomo.org (please do a search first as it might have been reported already)
It started just after upgrading to the 3.7.0 version.
Is it important?
Does someone know how to solve that?
Hi there, this was fixed in https://github.com/matomo-org/matomo/pull/13463 . Will be fixed in next release.
