 * Hi,
 * The recent update to 4.5.2 seems to have eliminated a shopping cart wishlist 
   plugin on my website. I emailed the plugin developer, and I was told:
 * “This issue it is related to the last wordpress update which have a mini bug 
   with the jquery. If it is urgent follow this steps explained here [https://colorlib.com/wp/load-wordpress-jquery-from-google-library/](https://colorlib.com/wp/load-wordpress-jquery-from-google-library/)
 * and add the script the your theme functions.php
 * or i suggest to wait as will be an update soon of the wordpress which will fix
   this, so the plugin itself do not have issue
 * here the code :
 * //Making jQuery to load from Google Library
    function replace_jquery() { if (!
   is_admin()) { // comment out the next two lines to load the local copy of jQuery
   wp_deregister_script(‘jquery’); wp_register_script(‘jquery’, ‘[http://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js&#8217](http://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js&#8217);,
   false, ‘1.11.3’); wp_enqueue_script(‘jquery’); } } add_action(‘init’, ‘replace_jquery’);
 * What do you guys recommend? I’m not a coder, so what I do know is that the plugin
   stopped working right after the update, otherwise it was fine. Any help or suggestions
   would be great. If you think this is an appropriate action, or perhaps to use
   an older version of functions.php, then please let me know.
 * Thanks!

 * It’s actually up to the plugin’s developer to fix.
 * See [https://wordpress.org/support/topic/read-this-first-wordpress-45-master-list?replies=7&view=all#post-8271654](https://wordpress.org/support/topic/read-this-first-wordpress-45-master-list?replies=7&view=all#post-8271654)
   for the big details.
 * The short version is that some plugin and theme developers have been using jQuery
   incorrectly (not following documented standards) for a while. jQuery recently
   decided it was time to “fix” the vulnerability that was being exploited, and 
   now that incorrect usage no longer works. The latest version of WordPress includes
   that latest version of jQuery.
 * We have no plans to revert to an old version of jQuery, so developers will need
   to update their products to use jQuery properly.

 * Ah, okay, thanks for letting me know. I’ll got back to the developer and see 
   what I can do there. I did pay for that script, so they do indeed have to do 
   something about this, for sure. Thanks!
