[Help]Joomla 2.5 Undefined variable: mainframe print?

[ladydevil]

Hi everyone.
When I use Joomla 2.5:
"Joomla 2.5 Undefined variable: mainframe print"
How to fix it?
Thank you very much.!

Are you using the latest 2.5 version, 2.5.24?

Thank Toivo. I got the answer from a friend:
To fix your problem add in line 4:
Code:
$app = JFactory::getApplication();
and then replace line 23 with the following:
Code:
<a href="/index.php" class="logo"><?php echo $app->getCfg('sitename') ;?></a>
Also I noticed your template has a potential java script injection. To fix this, replace line 13
Code:
<link rel="stylesheet" href="/<?php echo $this->baseurl ?>/templates/<?php echo $this->template ?>/css/<?php echo $this->params->get('colorVariation'); ?>.css" type="text/css" />

$mainframe is Joomla 1.5 variable. You must be using an outdated template or extension.
