You need to find/replace compiled code. If the enter the following, you can see what the compiled code looks like:

PHP Code:

echo $vbulletin->templatecache['newthread']; exit; 


In your case, you would use this:

PHP Code:

$vbulletin->templatecache['newthread'] = str_replace(
    "' . $forumrules . '",
    '',
    $vbulletin->templatecache['newthread']
); 


But since $forumrules is a variable containing a rendered template, you can empty it instead.

PHP Code:

$forumrules = '';
