@glenn – Sorry for the delay, I am one of the organizers for WordCamp Jacksonville FL which is this weekend so this week has been pretty hectic.
Your site is using Divi and it appears that the Divi themes custom.js file has a jQuery error likely due to WP Core updating to the latest version of jQuery and Divi needing to update to match.
See here near the bottom about jQuery Libraries: https://www.ads-software.com/news/2016/04/coleman/
That aside I do not see a popup loaded on that page so if you disabled it just know that the error is not in Popup Maker but Divi, this is the 3rd report in 2 days with the same cause.
I have tested thouroughly both 1.3.9 and v1.4 beta against WP 4.5 and saw no PHP or JS errors. I have been using the WP4.5 betas on my local dev server for weeks and haven’t even seen any issues with our extensions so that Divi error is the likely cause.
Check it yourself using your browser console (F12 -> Console Tab -> Then Refresh and you will get more details).
This is the offending line: $( ‘a[href*=#]:not([href=#])’ ).click( function() {
And the error: jquery.js?ver=1.12.3:2 Uncaught Error: Syntax error, unrecognized expression: a[href*=#]:not([href=#])
@aquor – Your site seems to have a JS error as well for something called WP Scroll Depth. You can get more info from browser console as well.
Hope that helps.
