I've tried to set up the WordPress SEO plugin to generate a sitemap and have managed to open in Webmaster Tools but am getting a great number of Warning messages that the URLs are being blocked by robots.txt file. I cannot seem to see a robots.txt or sitemaps in my ftp client. Obviously something is wrong and I have no idea how to fix it. I am using the latest version of WordPress and am using the Headway theme (latest version).
Hope someone can help - I really like the plugin and if I can get the sitemaps working it would be perfect.
