I seem to run into this problem frequently and can never find a solution. I have a Wordpress site with a top navigation. Since this is in my header.php, and used on all page
try something like this:
'About Us', 'blog' => 'blog') ?>
$page): ?>
- >
">
It may be worth looking into using wordpres functions such as get_page_link which would be nicer than using the Server super global as that's not nice. This would also fail if you have wordpress in a folder and not the document root, it's just a simple example to get you started :)
