RavanH on "[Plugin: Easy FancyBox] Not Working After 4.5.2 Upgrade"

Hello, after upgrading my website to 4.5.2 I am having issues.

The X to close out no longer works, they will only open the FIRST fancybox on the page no matter which is clicked, etc.

Here is a link to page that the issue is occurring on: http://veneers.com/veneer/composite-veneers/

Any help is appreciated. Thank you!

Hi, many people have reported issues since the upgrade and in every case it was caused by an error in jQuery from a theme script. And a theme update to make it compatible with jQuery 1.12 fixed it every time.

However, in your case it's not so clear.

I do see in your source code that you are including the jQuery library 5 (five! in different versions!) times:
http://veneers.com/wp-content/themes/brookside/effect/jquery.js
http://veneers.com/wp-content/themes/brookside/js/jquery-latest.js
http://veneers.com/wp-content/themes/brookside/js/jquery.max.js
http://veneers.com/wp-content/themes/brookside/js/jquery.min.js
http://veneers.com/wp-includes/js/jquery/jquery.js?ver=1.12.4

This should be just once. Preferably just the one included in WordPress (/wp-includes/js/jquery/jquery.js) ... Every additional loading of the main library is asking for trouble and makes debugging practically impossible.

Here are some resources with instructions on how to include jQuery in WordPress:

Long read (but instructional) https://premium.wpmudev.org/blog/adding-jquery-scripts-wordpress/
Official doc https://developer.wordpress.org/reference/functions/wp_enqueue_script/

I suspect after cleaning up all redundant/double inclusions of the jQuery library, the close button issue will be gone... If not, please let me know and I'll try to debug further.
