Thanks for all the help. I have seen something that I did not expect, the site is not that I have managed it for a long time, if I go to the page http://www.domain.com/sitemap… the sitemap appears to me and below the following text:
Generated with Google (XML) Sitemaps Generator Plugin for WordPress by Arne Brachhold. This XSLT template is released under the GPL and free to use.
This means that the sitemap (which is kept up to date) is being generated using the Google XML sitemap plugin (it’s a plugin I removed) ?
If so, how could I remove that sitemap and work with the Yoast?
