Here is the fix...

To fix the header issue, do the following:

In the PluhNews.php file REMOVE or COMMENT OUT
require("./global.php");

In the page where you want to display your news, insert this before ANY HTML
require("./global.php");

Go to your Admin Panel in vBulletin and under vBULLETIN OPTIONS
go to the section called HTTP HEADERS AND OUTPUT .

Find this section:

Cookie Domain
The domain on which you want the cookie to have effect.
If you want this to affect all of yourhost.com rather than just forums.yourhost.com,
enter .yourhost.com here (note the 2 dots!!!). Can be left blank.

ADD
.yourhost.com to the input box; save.

Your done.

This error was a combination of a few things. The cookies generated by vBulletin were part of the culprit as they were not being applied to any pages outside of vBulletin application. The second issue was that the global.php was being called twice by the [require('./admin/config.php');] by the PluhNews.php file.

I pretty much concluded that the error was either a cookie or a cache issue since the error was being generated randomly and on different machines. After that, it was just a case of sorting it out.

The author of this script should include this in his installation instructions. Would have saved me, and I am sure many others, wasted hours trying to figure out this error.

Enjoy!
