I have encountered a strange issue which I cannot seem to fix, hopefully someone will be able to shed some light on why this is happening.
I am using wp_nav_menu to display my primary navigation, however on category pages the menu does not display. All of the pages pull in the header using:
<?php get_header(); ?>
My wp_nav_menu looks like this:
<?php wp_nav_menu( array( 'container_class' => 'menu-header', 'theme_location' => 'primary' ) ); ?>
I have also tried the solutions found in the following thread however both solutions caused further issues:
Any help would be greatly appreciated,
