Problems with "hasPerm" function

[bladerunner]

The modification of the file "us_helpers.php", adding the declaration of the variable "master_account" as global inside the function "hasPerm", has worked for me. This way:

Code:

function hasPerm($permissions, $id) {

Code:

$db = DB::getInstance();

Code:

global $user;

Code:

global $master_account;   //THIS IS THE NEW LINE

Code:

//Grant access if master user

Code:

$access = 0;

Can anyone verify if this is a correct way to fix this problem, please?
