John Gardner on "[Plugin: Arconix FAQ] wordpress 4.5 questions and answers stay unfolded"

I use the faq plugin but I've updated WordPress and now all the questions and answers are unfolded and I get them no more folded.

Hi,

Thanks for using my plugin and I apologize for the troubles you're having. I've updated my demo site to WordPress 4.5 and my plugin still works as expected. Did anything else update at the same time? Do you have a link to the site where I could possibly see the problem in action?

Thanks for your reply.
No. I just updated WordPress.
The link to the site is http://klusje015.nl/faq-account/

I found a javascript error on that page which is preventing my plugin from working properly.

Uncaught Error: Syntax error, unrecognized expression: a[href*=#]:not([href=#])

I found that particular line of code in wp-content/themes/Divi/js/custom.js/. I'm not sure why it broke or how to fix that error, but I'm sure the guys over at ElegantThemes will be able to help with their theme.
