Editing "showthread.php"

[G0F0RBR0KE]

I'm trying to convert a modification from 3.5.x to 3.6.7

However, I think I got everything set up except for the .showthread.php

Find:

// ************************************************** ****************************** *
// check if there is a forum password and if so, ensure the user has it set
verify_forum_password($foruminfo['forumid'], $foruminfo['password']);

Add ABOVE:

// M/DD/YY PRIVATE THREADS PORT
include_once('./includes/functions_privatethread.php');
if (private_thread_not_allowed($threadinfo))
{
eval(standard_error(fetch_error('privatethread_not allowed')));
}
// END PRIVATE THREADS PORT

^^^^^ That for 3.5.x

So, how should it be for 3.6.x so it won't give a blank page?
