I install wordpress and checked “Discourage search engines from indexing this site”, but when I uncheck it, the xml setting is still available:The XML Sitemap is disabled because of your site’s visibility settings (above).

Hello.

Thank you for your simple but very useful plugin.

We found a problem while using it.

Is it possible to output as lastmod for each taxonomy tag news-tag /wp-sitemap-taxonomies-news-tag-1.xml as the date of the last addition of a post with this tag, and NOT the date of the last change of the tag itself.

Such a date of last modification of a page like /news-tag/dfgdfg would be more logical for Googlebot to bypass.

The solution to the problem could not be found – they only suggest deleting the XML Sitemaps Manager plugin and replacing it with an alternative solution.

Can you, as the author of the plugin, suggest a solution? Perhaps with the help of third-party code, but for it to work correctly in conjunction with the XML Sitemaps Manager plugin.

OK, if lastmod is enabled (which mine ISN’T anymore) it produces dates that are invalid.

But, there is yet another issue.. If the post does NOT have a date, this plugin will falsely add a CLOSING “<lastmod/>” WITHOUT an initial “<lastmod>”! See the below for just “https://storefly.com&#8221;

ALSO, speaking of the above, why on earth is this plugin picking up my top level domain?

There needs to be a way of excluding stuff like this.

Can we please get this fixed? I have you a 5 star review.

On one site, with this plugin enabled, the wp-admin crashes.

It seems the issue is in the file class.xml-sitempas-manager-admin.php on line 161. It should read:

$max_urls = get_option( 'xmlsm_max_urls', false );

(the false was ommitted)
