Template Variable Issue - class_core.php

[shri]

While debugging a problem where the variables cannot be accessed from the header template, I have narrowed this down to class_core.php.

On one forum where I'm able to access a variable (say $ForumMenu) in the header template, in around line 4074 of class_core.php I added the following code.

$template_name = preg_replace('#[^a-z0-9_]#i', '', $this->template);
if ($template_name == "header") {
var_dump($template_code);
}

Here, I can see this for example "misc html $ForumHome misc html" as an example.

On the forum where it does not work, I see "$final_rendered = misc html $ForumHome misc html".

Any ideas why the same header on one forum would show up as with the $final_rendered and the other would not?

Have I missed a step in the upgrade?

Please, I do need this resolved... spent dozens of hours trying to resolve this and am about to abandon 4.0 and move back to 3.8 for our new platform.

I assume I cannot ask vb support as they do not support mods or code related issues?? Any recommendations on how I might be able to get through to someone who could help?
