sitemap-post-type-post.xml

Hi,

Viewing the source of the generated XML sitemap, I found that you have a plugin that alter the XML output. Looks like it tries to minify the XML. But the size of the XML exceeds its limit, so it doesn’t work and output a comment, which is invalid in XML.

There are 2 solutions for that:

– Exclude the sitemap XML from that plugin. To do this, please find the plugin settings and see if there’s an option to exclude URLs.
– Lower the number of posts in the XML sitemap to reduce the size of the sitemap. To do this, please use this snippet:

add_filter( 'slim_seo_sitemap_post_type_query_args', function( $query_args ) {
    // Change number of URLs
    $query_args['posts_per_page'] = 500;
    return $query_args;
} );

Here I set the limit to 500, you can try to set a lower number to see if it works.
