Sitemap keeps giving 404

Good morning,
Thank you for your reply. Before asking for help, I already tried the now offered solution:
”
I tried flushing the perm links and adding sitemap.xml to the exclude list of my litespeed cache plugin,
”
As with these options it still does not work, I turned to you in order to see how I could find the reason why it is not working.

Thank you in advance.

Kind reagrds,

Hi,
Thank you for this tip! I tried to add the line in my functions.php file, but am not sure it is added at the right place. I added it here:

”
<?php

$thegem_use_new_theme_options = true;
$thegem_use_new_page_options = true;
$thegem_use_old_theme_options = true;
$thegem_use_old_page_options = false;

require get_template_directory() . ‘/inc/template-tags.php’;
require get_template_directory() . ‘/inc/options.php’;
if ($thegem_use_new_theme_options || $thegem_use_new_page_options) {
require get_template_directory() . ‘/inc/theme-options/theme-options.php’;
}
require get_template_directory() . ‘/inc/content.php’;
require get_template_directory() . ‘/inc/post-types/init.php’;
require get_template_directory() . ‘/inc/woocommerce.php’;
require get_template_directory() . ‘/inc/megamenu/megamenu.class.php’;
require get_template_directory() . ‘/inc/megamenu/megamenu-walker.class.php’;
require get_template_directory() . ‘/inc/image-generator/image-editor.class.php’;

require get_template_directory() . ‘/inc/pagespeed/pagespeed.class.php’;

require get_template_directory() . ‘/plugins/plugins.php’;

require_once ABSPATH . “wp-admin” . ‘/includes/file.php’;

if ( ! defined( ‘THEGEM_PAGE_EDITOR’ ) ) {
define( ‘THEGEM_PAGE_EDITOR’, ‘wpbackery’ );
}

if ( ! isset( $content_width ) ) {
$content_width = 1170;
}

if(!function_exists(‘thegem_setup’)) :
function thegem_setup() {
load_theme_textdomain(‘thegem’, get_template_directory() . ‘/languages’);
add_theme_support(‘automatic-feed-links’);
add_theme_support(‘post-thumbnails’);
add_theme_support(‘woocommerce’);
add_theme_support(‘title-tag’);
remove_theme_support( ‘widgets-block-editor’ );
set_post_thumbnail_size(672, 372, true);
add_image_size(‘thegem-post-thumb’, 256, 256, true);
add_image_size(‘thegem-custom-product-categories’, 766, 731, true);

‘max_posts’ => 6,
));
add_filter(‘use_default_gallery_style’, ‘__return_false’);

function thegem_jpeg_quality() { return 80; }
add_filter( ‘jpeg_quality’, ‘thegem_jpeg_quality’, 10, 2 );

if(!get_option(‘thegem_theme_options’)) {
update_option(‘thegem_theme_options’, thegem_first_install_settings());
delete_option(‘thegem_activation’);
}
add_filter( ‘rank_math/sitemap/enable_caching’, ‘__return_false’);
$thegem_theme = wp_get_theme(wp_get_theme()->get(‘Template’));
$option_version = thegem_get_option(‘theme_version’);

”

I flushed the Cash I could flush and re-did the original actions like changing the 200 number to 199, saving and re-initiate the perm links.

Still the 404 persists.

Was the location of the line wrong, or did I overlook something?

Kind regards,
