[ Closed ] Imprting punbb into cakephp

Hi,

I'm trying to import punbb into cakephp.

I have defined PUN_ROOT and included the file include/common.php

But a php fatal error jumps at me

Fatal error: Call to a member function query() on a non-object in ..../include/functions.php on line 125

I have var_dump($db) before line 120 on common.php
and its show me an object reference, but inside check_cookie() i get NULL.

For some odd reason the global $db doesn't work (also other global like $pun_user,$pun_config ....).
When overriding cakephp and running index.php or defining PUN_ROOT inside common.php and running it i get no error

Any idea why?

Thanks,

Assaf
