And did you already define $templatevalues as an array somewhere?

I added that line but it didn't fix the problem. And I haven't definre $templatevalues as an array anywhere.

Nope... just this plugin. And our host said that mod_security was blocking it but they whitelist it for us.

Problematic Webserver pops up with No to "Module Loaded" and "AJAX Unicode Issue".

Just a minor update. When I add your code:

vB_Template::preRegister('header', array('templatevalues' => $templatevalues));

This is the error I get:

Fatal error: Call to a member function render() on a non-object in /home/fpaul46/public_html/forum/includes/class_core.php(4257) : eval()'d code on line 2
