WordPress filters to make HTML password reset emails work

functions.php

<?php
// adding support for html emails
// this converts ALL wp_mail emails to HTML, which messes up the password reset email
add_filter( 'wp_mail_content_type','prefix_set_content_type' );
function prefix_set_content_type() {
        return "text/html";
}

// add this filter too
// this will make the password reset email compatible with the HTML format
add_filter( 'retrieve_password_message', 'prefix_retrieve_password_message', 10, 2 );
function prefix_retrieve_password_message( $message ) {
        // Revise the message content to make it HTML email compatible
        $message = str_replace('<','',$message);
        $message = str_replace('>','',$message);
        $message = str_replace("\n",'<br>',$message);
        return $message;
}
