  1. I think the problem is that wordpress changed the way the user activation key is saved in the database. The key is hashed before it’s saved in the wp_users table and $key contains the unhashed plain-text activation key. So the following line of your code won’t get a result and $user_login will be empty.

    $user_login = $wpdb->get_var("SELECT user_login FROM $wpdb->users WHERE user_activation_key = '$key'");

    Try this instead:

    add_filter ('retrieve_password_message', 'custom_retrieve_password_message', 10, 2);
function custom_retrieve_password_message($content, $key) {
global $wpdb;
$user_data = get_user_by_email(trim($_POST['user_login']));
$user_login = $user_data->user_login;
ob_start();
$email_subject = custom_retrieve_password_title();
include('email_header.php');
?>

<p>It looks like you need to reset your password for your account!</p>
<p>To reset your password, visit the following address, otherwise just ignore this email and nothing will happen.<p>
<a href="<?php echo wp_login_url("url") ?>?action=rp&key=<?php echo $key ?>&login=<?php echo $user_login ?>">Reset password</a> 

<?php
include('email_footer.php');
$message = ob_get_contents();
ob_end_clean();
return $message;
}

  2. I am not totally sure about all the rest . – but for one thing , you need to get your quotes right . try 

    echo wp_login_url('url')

    not 

    echo wp_login_url("url")

    e.g. :

    <a href="<?php echo wp_login_url('url') ?>?action=rp&key=<?php echo $key ?>&login=<?php echo $user_login ?>">Reset password</a>

    or try

    echo '<a href=' . wp_login_url("url") . '?action=rp&key='.$key.'&login='.$user_login.'>Reset password</a> ';

    Also – ( and if that is no help ) can you elaborate more where you use it , how and with what templates so we can try and dig deeper ?

  3. For anyone interested, this is another solution:

    add_filter ('retrieve_password_message', 'custom_retrieve_password_message', 10, 2);
function custom_retrieve_password_message($content, $key) {
global $wpdb;
if ( empty( $_POST['user_login'] ) ) {
     wp_die('<strong>ERROR</strong>: Enter a username or e-mail address.');
 } else if ( strpos( $_POST['user_login'], '@' ) ) {
     $user_data = get_user_by( 'email', trim( $_POST['user_login'] ) );
 }else if(!empty( $_POST['user_login'] )){
     $user_data = get_user_by('login', trim( $_POST['user_login']));
 }elseif ( empty( $user_data ) ){
     wp_die('invalid_email', __('<strong>ERROR</strong>: There is no user registered with that email address.'));
 }
$user_login_name=$user_data->user_login;
ob_start();
$email_subject = 'Your password has been changed';
include('email_header.php');
?>
<p>It looks like you need to reset your password. <br/>To reset your password, <a href="<?php echo wp_login_url("url") ?>?action=rp&key=<?php echo $key ?>&login=<?php echo $user_login_name; ?>">click here</a>, otherwise just ignore this email and nothing will happen.<p>

<?php
include('email_footer.php');
$message = ob_get_contents();
ob_end_clean();
return $message;
}

  4. Additionally, you can use the POST data to check if the username or the email was submitted:

    add_filter ('retrieve_password_message', 'custom_retrieve_password_message', 10, 2);
  function custom_retrieve_password_message($content, $key) {
    if ( username_exists($_POST['user_login']) ){
    $user_login = $_POST['user_login'];
} else {
    $user_data = get_user_by_email(trim($_POST['user_login'])); 
    $user_login = $user_data->user_login;
}
    ob_start();
