I installed wpmudev, along with some plugins using the control panel. Several of them now show up for blog owners, even though the plugins have not been activated by the network admin id.
This is happening for the plugins:
Q&A – WordPress Questions and Answers Plugin
Remove Permaklinks Menu Item
They are all inactive in the network plugin, but on the user’s list of active plugins, they all show up. I was even able to activate one (as a blog owner) even though the network owner had not activated it.
