After disable plugin in global it still working

What do you mean by specified site? Each site has it’s own settings in a network install. So you would need to disable the plugins globally on each site.

Hello Jeff
Thank you for answer!
Yes I think I understand the logic of this.
I go to Plugin “Organizer” -> “Global Plugins” -> switch “Contact Form 7” to off-> save and clean cache
and after this part, plugin contact form 7 shouldn’t work (shows) on my site until I don’t activate it on particular site. Am I right ?

Yes you are correct. Did you check that you have the MU plugin file in the right place? When you go to the plugins page in the network admin you should see a link next to All, Active, Inactive that says Must Use. If you click that link you should see Plugin Organizer MU listed. If you don’t see that then the file isn’t in place. You can go to the Plugin Organizer settings page and click the Manage MU Plugin File tab. Then click Copy. Or you can manually copy the file from /wp-content/plugins/plugin-organizer/lib/PluginOrganizer.class.php to your mu-plugins folder. Which should be located at /wp-content/mu-plugins/. If that doesn’t exist create it.

I already checked it in first place after install. File PluginOrganizer.class.php was added automaticly during installation to folder /wp-content/mu-plugins/ so everything looks fine. I checked this “must use” page in plugins site and Plugin Organizer shows there, but still after disable no matter which plugin in global plugins this disabled plugin shows in my site.

Hi Jeff,
Very very sorry for this question… I overmissed that in option after install plugin settings-> Selective Plugin Loading is turned of by default.
After activate it it’s work.
Thank you for support !

Oh yeah. I didn’t think about suggesting that. Glad you got it fixed.
