Hello,
thank you very much for the support. The tips with the code snippets was very useful.
Hello,
the steps described are not my problem. I’ve done all of them. Nevertheless, the content of the product sitemap include the last modified date only changes when I manually change the links per sitemap in the sitemap settings, not automatically when I’am post Woocommerce products. I’m thinking, the cache of the sitemap are not update automatically. The number of products does not change in Woocommerce, the last modified date does weekly.
