title: Blank screen on system configuration in admin panel for Magento
body: <p>We have encountered a problem with our site.</p>
  
  <p>The system > configuration screen only displays the menu, side menu and footer. When we click on side menu option, the screen remains black and the relevant information does not appear. Please see  <a href="http://www.featuredeco.co.uk/media/config_screen.jpg" rel="noreferrer"> this link</a>. This is what appears. When we click on any side menu option, the screen is blank</p>
  
  <p>This is causing a major problem as we are unable to access the information for configuring the site.</p>
  
  <p>Kind regards Paul</p>
