Hi,

It should let you navigate to the forum page... Maybe this works
better:

function checkReferrer()
{
if (isset($_SERVER['HTTP_REFERER']) && preg_match(
'#^https?://' . preg_quote($_SERVER['HTTP_HOST'], '#') .
'(/|$)#i', $_SERVER['HTTP_REFERER'])) {
return true;
}
header('Location: /');
return false;
}

Try var_dump($_SERVER['HTTP_REFERER']) when the link is clicked to
troubleshoot it.
