A friend of mine told me his new WordPress site didn’t work anymore after upgrading to WordPress 4.5.2
I investigated the issue and found out that all kinds of sliders were breaking in WP4.5. I followed the trail on the internet and came across following post https://wordpress.org/support/topic/wordpress-45-completely-breaks-all-sliders-all-themes. This helped me to identify the problem for my friend and I resolved it by changing the line of JavaScript code from this: a[href=#]:not([href=#]) to THIS: a[href*=”#”]:not([href=”#”]). I also installed following plugin https://wordpress.org/plugins/use-google-libraries/ and now everything works again!
