Regardless of whether the SEO plugin is enabled, the site will have an initial sitemap in XML format. This card is required by search engines and has its own format.
It is located at: your_site_name/sitemap.xml
Without the SEO plugin, only the main page of the site is displayed in the map.
When the SEO plugin is enabled, the map is displayed depending on the settings.
It is worth noting that when the updаte mode is enabled, the sitemap, regardless of the SEO plugin settings, will display only the main page.
The sitemap is a virtual page. You should not look for it on the server. If you upload a real file to the server, the contents of the real file will be displayed.
