title: website is going to 404 error page
body: <p>On this website I am building for wordpress, the footer.php file that I am editing I can't seem to fix one of the links.</p>
  
  <pre><code>&lt;a href="&lt;?php echo site_url(); ?&gt;/contact-us/" class="btn btn-black text-uppercase pull-right"&gt;Contact Our Office&lt;/a&gt;
  </code></pre>
  
  <p>When i click on the link it goes to a 404 page, and yes a contact-us page is real.</p>
