since I have upgraded to Matomo 3.11.0, the following warning sporadically shows up on the Diagnostic > System Check page:
WARNING: plugins/CustomVariables/CustomVariables.php(82): Notice - Undefined index: CustomVariables.MaxNumCustomVariables - Matomo 3.11.0 - Please report this message in the Matomo forums: https://forum.matomo.org (please do a search first as it might have been reported already)
I don’t use CustomVariables at all. It’s disabled on the plugins page. Any ideas?
Guess that's caused by disabling the plugin. Seems other plugins use methods of that plugin that don't work properly when the plugin is disabled
It could be. Besides Matomo Core plugins I do not use any additional plugins. I haven't noticed any issues when CustomVariables is disabled.
