    Hi,

    My website works fine and I can log in to admin succesfully. But for some reason when I go to appearance -> Menus I get the message below on a white screen and I cannot access the menus settings. Do you know what could be wrong? I only have 3 plugins – Elementor, Elementor Pro and Duplicator, all of which are updated.

    Fatal error: Uncaught Error: Call to undefined function _wp_expand_nav_menu_post_data() in /www/doc/www.pbtest.cz/www/tmcb/wp-admin/nav-menus.php:58 Stack trace: #0 {main} thrown in /www/doc/www.pbtest.cz/www/tmcb/wp-admin/nav-menus.php on line 58
    There has been a critical error on this website. Please check your site admin email inbox for instructions.

    That is a core WP function so should be there

    check if you have the file

    /wp-admin/includes/nav-menu.php

    and that contains

    function _wp_expand_nav_menu_post_data

    The file is completely empty. Ok so that would be my fault when I copied the files to the host. Thank you for your reply. Next time I will check the file first before I start panicking.
