Upgrade to Pub Suite broke a few things

[obscurecloud]

I just upgraded to Pub Suite and got to the point where support wouldn't help me any more.

The problem is that the blog.php, search.php and entry.php are showing white pages in some situations. The forums and CMS have no noticeable issues other than search.php.
The site www.fronttowardsgamer.com
The blog.php will display with certain variables attached to the URL (do=bloglist for example) but not others.
I've isolated the problem to be a plugin that displays the Wordpress header

ob_start();
include('../wp-load.php');
include('../wp-content/themes/mystique/header2.php');
$globalHeader= ob_get_contents();
ob_end_clean();

$preRegister['globalHeader'] = $globalHeader; 
vB_Template::preRegister('header', $preRegister);

With this added to the header tempalte

{vb:raw $globalHeader}

When I disable the plugin, blog.php seems to work just fine. I've been through the troubleshooting for white pages. I need to be able to display the WP header and need the blog to work as that is why we upgraded.

Any thoughts on this would be greatly appreciated.

blog.php?do=bloglist works fine but
blog.php gives me a white page.

search.php?searchid=4381 (what's new link) gives me a white page
search.php?do=process works just fine.

What about the plugin would make this happen?

I disabled the CMS and Blog plugins and still get the white pages.
