One thing I forgot to mention is that this change only addresses the use of a separate Add Post page using the wpuf_addpost shortcode.

Some consideration also needs to be given to using this as an in page editor like the “Reply” form at the bottom of this page. In this case the Close button isn’t appropriate but you would always want to be redirected back to the original page after login or post.

More thoughts on this later.

Slight correction and additional info

The original script at the top of the last post should be

Original

function showtime_jQuery_method() {
    wp_deregister_script( 'jquery' );
    wp_register_script( 'jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js');
    wp_enqueue_script( 'jquery' );
}    

add_action('wp_enqueue_scripts', 'showtime_jQuery_method');

To fix the offending plugin if it is compatible with JQuery version 1.7.2 alter the plugin code appropriately using one of the following options as a template

Option 1.

function showtime_jQuery_method() {
//    wp_deregister_script( 'jquery' );
//    wp_register_script( 'jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js');
    wp_enqueue_script( 'jquery' );
}    

add_action('wp_enqueue_scripts', 'showtime_jQuery_method');

Option 2

function showtime_jQuery_method() {
    wp_deregister_script( 'jquery' );
    wp_register_script( 'jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js');
    wp_enqueue_script( 'jquery' );
}    

add_action('wp_enqueue_scripts', 'showtime_jQuery_method');

Update1

Checked the admin editor load and found it was executing the following jquery file

file: wp-includes/js/jquery/jquery.js?
version: 1.7.2

In this file there is the following line which is executed on editor load.

f.curCSS=f.css

In the unminified version of this file this reads as

// DEPRECATED in 1.3, Use jQuery.css() instead
jQuery.curCSS = jQuery.css;

Commenting this out produces the same behaviour as the WP User Frontend exhibits on clicking the link button.

Found WP User Frontend wasn’t using this JQuery file at all. Instead it uses

http://ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js?ver=3.4.2

which is JQuery version 1.8 which doesnt include “jQuery.curCSS = jQuery.css;” and hence the problem.

So the real problem is why is WP User Frontend using the googleapis version and not the local wp-includes version? Which should it be using?
