title: Facebook application now getting "404 Not Found"
body: <p>I have a simple facebook application that serves content off of my primary web server.  I've integrated tabs into my facebook page that accesses this application.  It all worked perfectly. Now, suddenly, I get a "404 Not Found" error on my primary facebook page.</p>
  
  <p>The application itself works fine:</p>
  
  <p><a href="http://apps.facebook.com/composerseries/" rel="nofollow">http://apps.facebook.com/composerseries/</a></p>
  
  <p>But when accessed from within my facebook page as a tab, it now gives the error:</p>

  <p>I'm stumped.  I've changed nothing, so it must mean they've recently changed something.  Any help would be appreciated.</p>
  
  <p>Thanks,
