404 page showing in sitemap

Hi there,

Thanks for the follow up.

I would suggest that you enable WP_DEBUG and WP_DEBUG_LOG by setting these constants to true on your wp-config.php file.
This will then log all the error on your site on debug.log on the wp-content folder. Please check for any errors reported and fix them.

Thank you.

Hi Rajdeep,

Thanks for the question.

This could be one of the reasons, you can fix that by modifying the code to:
$path = $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];

I hope this info helps. Thank you.

HI Rajdeep,

The errors were related to the above, undefined constants.

I did not make other changes.

Thank you.

HI Rajdeep,

Thanks for getting back to us and sorry for the inconvenience caused.

The sitemap is working correctly when I check at this time which makes this issue very strange. Since this is causing an issue on your server, I would suggest that you disable the sitemap module and install the following plugin https://wordpress.org/plugins/google-sitemap-generator/ instead.

I hope this info helps. Thank you.
