title: Get hacked Joomla back on the rails
body: <p>I have an old joomla installation which was hacked. All I know for now only index.php was changed and they messed with my user accounts. I downloaded index.php from the current version but at one point it calls <code>$app-&gt;dispatch();</code> which requires a component name parameter in my version. Does anyone know what parameter this should be? I tried: null, 'home', 'application',...</p>
  
  <p>Also I'm planning on updating to the newest version later, however I can't seem to find my current version number. I found somewhere that it is displayed in the admin pages but I can't access them yet. Can I find it in the code files somewhere?</p>
  
  <p><strong>EDIT:</strong> The index.php from version 1.5.22 worked. Apparently the correct version was 1.5.3. Does anyone know what else I should check that might have been hacked/messed with?</p>
