Hi, i´m stuck where i´m supposed to paste code into /templates/mytemplate/index.php, I use yoo theme template and index php looks like this:
<?php /**
* @package yoo_planet Template
* @file index.php
* @version 5.5.4 October 2010
* @author YOOtheme http://www.yootheme.com
* @copyright Copyright (C) 2007 - 2010 YOOtheme GmbH
* @license YOOtheme Proprietary Use License (http://www.yootheme.com/license)
*/

// no direct access
defined('_JEXEC') or die('Restricted access');

// include config
include_once(dirname(__FILE__).'/config.php');

//find the content in /layouts/template.php

echo $warp->template->render('template');

i don´t know where to paste the code, since there are no head or body tags.

Thanks for the help in advanced

Which version are you trying to install

The pasting code method in template is not recommended .
If you are installing FreiChatX 5.1 then use the modular installation
since it does not require editing templates ,and is much easier.
