Hello,

your website returns http code 500 (error) for all requests, although content is returned correctly:
https://www.xml-sitemaps.com/http-headers-viewer.html?op=http-headers-viewer&go=1&pageurl=http%3A%2F%2Fwww.webtales.org%2F&se=xmlsitemaps&submit=View

You need to contact your host or site developer to correct this.
