I deactivated my coming soon plugin to troubleshoot an error possibly related to Pro Sites, so I decided to use the Multisite Privacy plugin to keep visitors out for now. After trying a few settings I see the following in my error log:

Other active plugins: Pro Sites, Defender Pro, WPMU DEV Dashboard.
On the main site, where I locked visitors out, I’m using one of the default WordPress themes.
I will deactivate the plugin, but at least wanted to let you know =))
