Pop up not showing up on my site

I just installed the WordPress PopUp plugin. I added a picture and a Call to Action button. I have no no conditions set. I wanted it to only be displayed on our home page but when I tried to set the condition for the URL specifically being our home pages url it wasn't showing up so I got rid of it so there's no conditions yet it's still not being displayed. (I've checked on other users computers as well).
