I'm putting together a custom theme for a client; it's online at http://beta.siegefitness.com right now. The menu doesn't seem to be conforming to what I indicate in the Menus control panel. Specifically, all pages are showing up alphabetically regardless of whether or not they've been added to the menu.
I've called the menu in header.php using the following code:
<?php wp_nav_menu( array( 'theme_location' => 'header-menu' ) ); ?></div>
Am I missing something?
