After the latest update to Enhanced Media Library (v1.1) I am unable to use the Customize page of WordPress as the widgets do not appear.
When I have the plugin enabled the sidebar looks like this:

This is clearly caused by the latest update to the plugin as everything was working fine before running the update.
