Popup Pro is not working at all…

I just enable the new PopUp Pro (I have the old version before major update, and then I disable it and never use it until now), both in my local site or Live site are NOT WORKING!

In my live site, I just create a pop up and click save, it did not save my popup post. Instead, it just generate a AUTO post.

Please help!

Also, my entire site JavaScript is breaking. Google Console throw this error:

Uncaught ReferenceError: _popup_data is not defined public.min.js?ver=4.0.1:4

I have to disable the plugin.
