Request was meant for a plugin which is no longer activated

On a fresh install of the latest version of Matomo, after configuring the first container I found this error in the log files of my NGINX server:

2023/09/01 06:40:38 [error] 73575#73575: *383089 FastCGI sent in stderr: "PHP message:

upstream: "fastcgi://unix:/run/php/php8.2-fpm.sock:", host: "matomo1.domain.com",

I am referring to the Request was meant for a plugin which is no longer activated bit. My only three inactive plug-ins are:

  • DBStats (Core)
  • Feedback (Core)
  • MobileAppMeasurable (Core)

The only plug-in I installed myself was SecurityInfo (v4.0.2).

Anyone knows why this is happening? Do I need to install some additional plug-in that may be available in the Cloud version of Matomo?

Thanks in advance.
