Popup Will Not Display | WordPress.org

I have tested the plugin on another site and it works fine. I cannot get it to work on this site. I have created a staging site and deactivated all plugins and it still does not work.

The only difference with this site and the other is this one is a child theme.

Do you have any insight as to why this would not work?
