@dpotter05 – Sorry to hear that, sounds like you may have benefitted from submitting a support ticket.
From just the info you have provided I would deduce that you probably did set it up correctly, as thousands of others have done, but may have another underlying issue that we can’t account for. There are dozens of known issues caused by even the most reputable themes & plugins. With the changes in WP 4.5 hundreds of themes suddenly had JS errors on every page. This isn’t an issue for the average Divi user, but for the ones that use other JS based plugins like Popup Maker it prevents our JS from ever running.
With so many possible issues out there, if you followed the guides which we both know you did, then likely the issue isn’t in Popup Maker at all.
Also unless you tried Easy Modal not sure reviewing it negatively back to back is fair either, if neither plugin worked, then I can assure you something else is wrong on your site, but not presenting since nothing else on your site is breaking by appearance. I say this because there are collectively 70k+ websites using the plugins, any issues in our control are closely watched and patched quickly.
Now that said if you have a link I would be happy to look at it, but I am assuming that you have moved on and will not revist the issue, though I hope you do so we can resolve it one way or another.
In any case, check your site for JS errors using the browser console as well as PHP errors. Never know what your going to find.
