XML sitemap preview error in browser

Ran into the same issue. It seems to be happening because the title separator is outputted as an entity name (eg –) instead of entity number (&#8211) – at least in Custom Post Type feeds.

A similar issue was reported and fixed about two years ago.

Tested with the latest Yoast version, 19.14 and 19.13.

I dug a little deeper to find out the possible cause for this.

It looks like the use of pre_get_document_title filter short-circuits the wp_get_document_title , which has filter document_title_separator.

That document_title_separator filter is used on feed-imporvements.php file to decode entities. But since the whole title generation is short-circuited, said filter is never used.

The following code, added to the theme, fixed it for now.

add_action( 'get_wp_title_rss', function( $title ) {
   return html_entity_decode( $title );
} );

I believe Yoast should do something similar in feed-imporvements.php instead of using document_title_separator filter.

Hello @antcrescendo

I’m sorry abpout the declaration error in your sitemap. This happens when an empty?whitespace or a blank line appears due to a conflict with another plugin or your theme. Usually, there is an empty space or a blank line before or after the closing PHP opening or closing tag, which shouldn’t be there.

You can narrow down the exact source of conflict by performing a conflict check. Once you have identified whether your theme or a plugin causes the issue, please contact the developers of that theme or plugin for assistance in finding and removing the white space.

This thread was marked resolved due to a lack of activity, but you’re always welcome to re-open the topic. Please read this post before opening a new request.

Hello @maybellyne, I created a troubleshooting test environment with the “healthcheck and troubleshooting” plugin and Yoast is the only plugin?I have enabled, but it still gives me the same error when I preview my XML sitemap.

Although I disabled all of the plugins to rule out any potential conflicts, it appears that I am still encountering the same XML sitemap error.

List of plugins: https://postimg.cc/MMPzznbt

You will see in the screenshot above that all my plugins are disabled besides Yoast and the Health Check plugin.

I am also using the Twenty Twenty-Two theme version 1.3

Yoast Version 19.14

I do have the same problem with – I run wordpress version 6.2.2 , yoast version 20.8

For the moment I fixed the trouble with the solutions provided by @sippis

Thank you Timi Wahalahti !

Had the same problem with – title separator. Either choose normal dash or use the temporary workaround provided by @sippis

Both solutions worked for me.
Thanks!
