Ajax call in wordpress not working for subscriber user

Question

All

In my application there is notification system, when user click on that icon I want to make ajax call. The problem id it works fine for admin user (Debug : 200 ok), but not for subscriber user (Debug : 301 moved permanently).

Ajax call

$("#notifications-button").click(function() {


    $.ajax({
    type : 'POST',

    url: '<?php echo get_option('siteurl') . '/wp-admin/admin-ajax.php' ?>',
    data:'action=my_special_ajax_call&value=1',
    success : function(data){
        $('.message-count').hide();
    },

    });
});

Function

 function implement_ajax() {

if(isset($_POST['value']))
  {

    global $wpdb, $user_ID;

    $wpdb->query( $wpdb->prepare("UPDATE wp_frm_items SET alerts_flag = 0 WHERE user_id = '". (int)$user_ID ."'" ));
}
}
add_action('wp_ajax_my_special_ajax_call', 'implement_ajax');
add_action('wp_ajax_nopriv_my_special_ajax_call', 'implement_ajax');//for users that are not logged in.

I do not able to get why this not working for subscriber? Is there anything wrong in code?

Thanks In Advance !

Answer 1

The problem is a conflict with the plug-in Role Scoper. Deactivating the plug-in resolves the issue. As an alternative to Role Scoper, (I do not offer this as a recommendation, simply a suggestion), there is the plug-in Members.

Solving by make manual ajax call to test.php page

<?php 

ini_set('html_errors', 0);
define('SHORTINIT', true);

require '../../../wp-load.php';
require( ABSPATH . WPINC . '/formatting.php' );
require( ABSPATH . WPINC . '/meta.php' );
require( ABSPATH . WPINC . '/post.php' );
wp_plugin_directory_constants();

// stuff goes here

if(isset($_POST['value']))
  { 

    $uid=$_POST['value'];
    global $wpdb;
    $wpdb->query( $wpdb->prepare("UPDATE wp_frm_items SET alerts_flag = 0 WHERE user_id = $uid" ));
}
?>
