I used to manage user plugins by this plugin-manager - http://wpmudevorg.wordpress.com/project/Plugin-Manager
I dont know which theme or plugin conflict, so far I still can not “Globally Deactivate”. the plugin still work and show on "Check active plugins".
since it no function for my WPMU, I try find out database but not found how to deactive all plugin using by blogger.
any idea for SQL command to deactive all plugin? thanks
