Max Mega Menu not working on a site

Hi there Tom,

The website I have a problem with is http://www.dharrison.org.uk/

I am using the ultimatum theme to build this website and it has the following code in the functions.php child theme.

add_action( ‘init’, ‘register_my_menus’ );

function register_my_menus() {
register_nav_menus(
array(
‘primary-navigation’ => __( ‘Primary navigation’ ),
)
);
}
add_action( ‘init’, ‘register_my_menus’ );

the following code is placed in the header template where I want the max mega menu to show up:

<?php wp_nav_menu( array( ‘theme_location’ => ‘primary-navigation’ ) ); ?>

I think this may be a conflicting problem between the Ultimatum theme and the max mega menu. Is there any way to isolate it to work.

I have built a number of websites containing your brilliant plug in and have not had this problem before.

Kind regards
John
