I have WordPress hosted on a Windows server. I created the two sitemap files manually and set full permissions on each. If I rebuild my sitemap manually (from the Rebuild option) it is fine, if however I change some content, when I go to the sitemap config page I have errors saying it couldn't write to the files (and the sitemaps are NOT updated)....
Can anyone help me?!
