title: Drupal White Screen of Death WHOD
body: <p>I added a header for a view in Drupal 7 (PHP 5.6). I used PHP filter in the view header to add the PHP code for pytting a 'add content type' button on the view page. When I saved the view, the site gave me a blank screen. This happened to me quite a number of times. Now, since the site is not accessible I am not able to remove this code from the view header.
  Is there any way to revert the white screen in drupal?</p>
