[Triky]

When I create the plugin and I activate it, I get a blank page in my forum. This is the code I'm using in the plugin:

PHP Code:

ob_start();
  require_once('../includes/kbar.php');
  $kbar = ob_get_contents();
ob_end_clean();
vB_Template::preRegister('header',array('php_include' => $php_include)); 


And this is what I'm using on the template header:

{vb:raw kbar}

Why? Can you please help me?
