It seems I can only install plugins from the Network Admin panel, and not under any of my sites, even when I'm logged in as admin. And if I do install a plugin, the new plugin doesn't show under any of the individual sites, even if I network activate it. I'm a bit confused, since I was just installing plugins yesterday with no problems then suddenly today it doesn't work. I had created a new site today, but do not know if it worked before creating the site. Anyone seen this before? I have the site admin Plugin option enabled in the network settings. Thanks!
