Published Date and Author Customization

I used below PHP code below to customize the author and published date (entry-meta) and want to reposition it from its default position below the thumbnail (title – thumbnail – entry meta). But I don’t know why the function of repositioning stops working. Is there even an easier way to achieve this function?

// Modify the post author and date output
add_filter(‘generate_post_author_output’, function () {
return sprintf(
‘%1$s’,
sprintf(
‘Author: %s’,
esc_html(get_the_author())
)
);
});
// post date
add_filter(‘generate_post_date_output’, function ($output, $time_string) {
$time_string = ‘%2$s’;
$time_string = sprintf(
$time_string,
esc_attr(get_the_date(‘c’)),
esc_html(get_the_date()),
esc_attr(get_the_modified_date(‘c’)),
esc_html(get_the_modified_date())
);
return sprintf(
‘

Published Date: %s’,
$time_string
);
}, 10, 2);

add_filter(‘generate_header_entry_meta_items’, function () {
return array(‘date’, ‘author’);
});

add_filter(‘generate_footer_entry_meta_items’, ‘__return_null’);

//reposition
function tu_move_posted_on() {
if (is_single()) {
remove_action(‘generate_after_entry_title’, ‘generate_post_meta’, 10);
add_action(‘generate_after_entry_header’, ‘generate_post_meta’, 20);
}
}
add_action(‘init’, ‘tu_move_posted_on’);
