In your main root (htdocs/wwwroot) look for "index.php". Delete all of whats inside the file, and replace it with this below;
<?php
define('IN_INDEX', 1);
require_once 'global.php';
$core->handleCall($engine->secure($_GET['url']));
$template->html->get($engine->secure($_GET['url']))...
It means that the "AboutCommand2" doesn't exist / couldn't be found, make sure at the top of your command it says AboutCommand2 here; http://prntscr.com/iv1626
Does your habbo.swf exist in the gordon folder? , If you have a production folder inside your gordon folder, don't forget to add that e.g.
{url}/swf/gordon/PRODUCTION-Whatever-Whatever
If it's just the gordon folder on it's own, just remove a " / " from somewhere.
