This should be in your functions.php to register the menu within WordPress.
if (!function_exists('wp_basicTemplateSetup')) {
function wp_basicTemplateSetup() {
// Register the Main Menus into WordPress
register_nav_menus(array(
'primary' => __('Main Menu', 'theme-name'),
));
}
}
add_action('after_setup_theme', 'wp_basicTemplateSetup');
In your theme, where the menu is sitting you need to tell the menu function, which menu to look for. So..:
// Variable that tells WordPress which menu to use, look at "Theme Location"
// Put this variable either at the top of your theme, of right *before* the function wp_nav_menu
$mainmenu = array(
'theme_location' => 'primary',
'container' => false,
'menu_class' => 'some-menu-css-class',
'depth' => 2
);
// The WordPress menu function
<?php wp_nav_menu($mainmenu); ?>
These 3 components are necessary to get your WordPress menu working.
