installing plugins and configuring with pro sites

Hi,

I'm just wondering why sometimes certain plugins show up if configured with pro sites and then some of them don't. For example. I've installed Floating Social. If I activate Network it works fine. If I deactivate and you levels with Prosites it doesn't work.

Either that or I'm not configuring plugins properly. This has happened to me with a few plugins.

Another one I'd like to use but not sure if it's supported is Social Media Widget.

Anyways. I do have them set in the levels and also for "auto activate" but no luck.

I'm trying to setup my template blog and I've given the blog full access and some plugins still don't show up in the admin.

I know some plugins aren't supported but floating social isn't working and I think I've got it setup properly. What am I missing?

Thank you!
