I am using this code

/*
==========================================
     Add category below de title
    ==========================================
*/

add_filter('generate_after_entry_title', function ($author) {
    echo $author;
    $category = get_the_category();
    $cat_name = esc_html($category[0]->name);
    $city = get_field('city', $post->ID);
    $date = get_the_date('j F, Y');
    if ($category) {
        echo '<span class="date">' . $date . '</span> | ';
        if ($cat_name === 'Events') {
            echo '<span class="country">' . $city . '</span> | ';
        }
        echo '<span class="categoriess">' . $cat_name . '</span>';
    }
});

When acf is not installed, inside the posts the content is not displayed. I can see the title only, why?

If I delete $city = get_field('city', $post->ID); the content is displayed again.

because this

$city = get_field('city', $post->ID);

is causing a fatal error call of an undefined function. Without ACF installed this function does not exist.
