title: Works in localhost but not when uploaded on server
body: <p>I have a problem...
  When I use</p>
  
  <pre><code>header('location: index.php?error=3'); 
  </code></pre>
  
  <p>It works in localhost but not in my website uploaded.
  I mean, in localhost everything goes fine, but online it doesn't change page, it load only half of the page and that's it, with no image, et cetera.</p>
  
  <p>EDIT:
  It does it with all header();</p>
  
  <p>Thank you.</p>
