	function mme_add_sitewide_link_in_wpfooter() {

	<div class="mme-sitewide-link">
		<h3><a href="">Name of Site</a></h3>

<?php }

	function mme_add_styles_in_wphead() {

	<style type="text/css">

	div.mme-sitewide-link {
		background-color: #000;
		margin: 20px auto;
		padding: 30px;
		text-align: center;
		max-width: 960px;
		width: 100%;

	div.mme-sitewide-link h3 a {
		color: #fff;
		font-size: 18px;


<?php }

add_action("wp_footer", "mme_add_sitewide_link_in_wpfooter");
add_action("wp_head", "mme_add_styles_in_wphead");


1. Create a new folder in server wp-content/plugins/ folder named mu-plugins
== > wp-content/plugins/mu-plugins

2. Create a new file named mme-sitewide-footer-link.php

3. Copy the code posted above, paste into mme-sitewide-footer-link.php and make sure that there’s no space at the top of or beside the first <?php

4. Change the link and name of site to your own site’s link and name in this line

<h3><a href="">Name of Site</a></h3></code> 

5. The style I made for the container of the link is black #000 and the text color is white #fff. Adjust and change to taste.

6. Save mme-sitewide-footer-link.php and upload to server wp-content/plugins/mu-plugins/ folder
