Floating Social Went Missing From My Homepage

I’m using the Floating Social plugin in a multisite installation. The plugin was working on the home page of a couple sites until a couple of days ago. I believe that the floating social box disappeared from this website (http://spaceunited.org/) and one other site within my multisite network after upgrading the plugin.

I have tried removing all other widgets from the home page, disabling and re-enabling the plugin network wide, turning on and off different social networks, and clicking the “Attempt to fix front page conflicts” button.

I can’t seem to get it back on the home page of my site.
