This plugin requires the Disqus comment system plugin to be installed…

Hi team,

Whenever I attempt to activate this plugin on a multsite network that I have, I get the following message: “This plugin requires the Disqus comment system plugin to be installed and activated on your WordPress site”.

This is despite the fact that I have Disqus installed. Is there anything I’m missing?
