TinyPortal

This time I really didn't search, sorry If I am re-reporting a error
Whenever I use SMF's Layering system when TP Is Installed I get loads of errors
Example of code is

$ssi_theme = 4;
$ssi_layers = array('main');
require_once(....../SSI.php);
echo 'test';
ssi_shutdown();

Mainly because TPortal_init is not called in SSI.php I believe.
So I used something like this
$ssi_theme = 22;
require_once('....../SSI.php');
TPortal_init();
template_main_above();
echo 'test';

ssi_shutdown();
