An exact match to the URL has been found with the Default Logged In settings.

That is a new feature to help you see what the plugin is doing. There is a link at the bottom of the notification to disable debug messages. By default only someone with the administrator role can see them. You can turn them off and then if you have problems later you can turn them back on with a button on the Plugin Organizer settings page. You can also give access to other roles so they can see the debug messages.

Thank you for your answer. I see that link. But what is causing this message?
And sorry for this late reply – i never got the notification that you answered.

You have a setting on a post or plugin filter that matches the page you are looking at. It’s letting you know that you have disabled plugins on that page.
