WordPress Front-end Editor plugin not working on multisite

This plugin is working if admin is logged in. It’s mot working on multisite when other user is logged in. When we click on ‘Edit Page’ tab its giving an error”This is somewhat embarrassing, isn’t it?
It seems we can’t find what you’re looking for. Perhaps searching can help” .
