Warning: call_user_func_array() expects parameter 1

    I had been creating a site on my local host and created an array of menus to use based on the page template I have used. It the local environment it all worked fine, however when I uploaded the site I got the following warning showing up at the top of my pages:
    Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘register_my_menus’ not found or invalid function name in /home2/rwvanleer/public_html/cedargoldmedical.com/wp-includes/plugin.php on line 524

    Here is a brief run down of what I did.

    In the functions.php page I added the following:
    register_nav_menus( array(
    ‘primary’ => esc_html__( ‘Primary’, ‘cedargold’ ),
    ‘cgls’ => esc_html__( ‘Labs’, ‘cedargold’ ),
    ‘cgac’ => esc_html__( ‘Accountable’, ‘cedargold’ ),
    ) );
    add_action( ‘init’, ‘register_my_menus’ );

    Once this was complete I added the following statement into the header.php file:
    <nav id=”site-navigation” class=”main-navigation” role=”navigation”>
    <button class=”menu-toggle” aria-controls=”primary-menu” aria-expanded=”false”><?php esc_html_e( ‘Menu’, ‘cedargold’ ); ?></button>
    <?php
    if ( is_page_template( ‘page-labs.php’)) { ?>
    <?php wp_nav_menu( array( ‘theme_location’ => ‘cgls’, ‘menu_id’ => ‘primary-menu’ ) ); ?>
    <?php
    } elseif ( is_page_template( ‘page-ac.php’)) { ?>
    <?php wp_nav_menu( array( ‘theme_location’ => ‘cgac’, ‘menu_id’ => ‘primary-menu’ ) ); ?>
    <?php
    } elseif ( is_page_template( ‘page-home.php’)) { ?>
    <?php wp_nav_menu( array( ‘theme_location’ => ‘primary’, ‘menu_id’ => ‘primary-menu’ ) ); ?>
    <?php
    } else { ?>
    <?php wp_nav_menu( array( ‘theme_location’ => ‘primary’, ‘menu_id’ => ‘primary-menu’ ) ); ?>
    <?php
    }
    ?>
    </nav><!– #site-navigation –>

    Again it works correct in local environment, no warnings.

    I would greatly appreciate any insights on how to correct this.

    Hello @rwvanleer,

    with add_action( ‘init’, ‘register_my_menus’ ); you are calling the register_my_menus function which is not defined – at least it does not appear in the code you pasted here.

    What you have to do is add the register_nav_menus into the function you specified:

    register_nav_menus( array(
    ‘primary’ => esc_html__( ‘Primary’, ‘cedargold’ ),
    ‘cgls’ => esc_html__( ‘Labs’, ‘cedargold’ ),
    ‘cgac’ => esc_html__( ‘Accountable’, ‘cedargold’ ),
) );

    like this:

    function register_my_menus() {
    
    register_nav_menus( array(
        ‘primary’ => esc_html__( ‘Primary’, ‘cedargold’ ),
        ‘cgls’ => esc_html__( ‘Labs’, ‘cedargold’ ),
        ‘cgac’ => esc_html__( ‘Accountable’, ‘cedargold’ ),
    ) );

}

    Again it works correct in local environment, no warnings.

    You might have different error reporting set on your local and live/staging site.
