Warning show up when using redirect($url, 'refresh');

You are not allowed to output anything to the browser before sending http headers. As to why it works on your local machine i don't really know. It shouldn't work .
If you really need to refresh the page after outputing a message, you could try a redirect using javascript

Code:

[removed]
   var newUrl = '<?php echo $newUrl;?>';
   setTimeout(function() {
      [removed].href = newUrl;
   }, 5);
[removed]

Or something like that
