Some of my installed plugins such as pretty plugins and the theme manager plugin are not transferring across multiple networks.
For example I cannot activate them on mulitple networks.
I am currently running 2 multisite networks under 1 wordpress installation. I have noticed that some plugins will work on the main/original multisite network (V), and not work on a secondary multisite network (Z) which, keep in mind, is still sharing the same database as the original mu network.
So both multinetworks share the same users, themes, plugins, etc but can function independently of each other, well most of the time at least. And some wpmudev plugins like the ones mentioned above seem to only work on a single mulsite-network installation.
