I had submitted a sitemap.xml file in google webmaster tools for one of my domains. The sitemap.xml have 98 url errors and when i check permalink structure is different in google webmaster tool with the one i have in sitemap.xml, if look sitemap xml file then permalink structure and url are working without any problem. I am using wp and google xml sitemap plugin, it had 1300+ pages indexed but now only 8 pages are index while sitemap has 4k pages
