Why the site does not open and writes "section not found"?

Question

1C-Bitrix

When a guest enters the site, nothing but the design is shown. Instead of a slider in the header "Section not found." Instead of page content, a site map.
The rights for the slider to read are worth it. For the directory, which is also displayed on the main page.

Answer 1

If you are sure that everything is ok with the rights, it means that your address generation settings (NC) are incorrectly configured. The sitemap displayed is most likely a 404 page that contains the sitemap.

Answer 2
