Sitemap Error: Missing XML tag
This commonly happens with the News SEO sitemap when a site has not published a news article within the last two days. It may also appear with the Video SEO sitemap if no videos have been made.
This required tag is missing. Please add it and resubmit.
This error appears when the sitemap contains zero items. Please create content for the sitemap. However, if you know you have made content you should clear/flush your cache from your website, plugins, theme, server etc.
