Alright so I just converted my site into WP format. My previous sitemap.xml file was made with an online sitemap generator. Its URL is http://www.mydomain.com/sitemap.xml. Google likes this and it's in Google Webmaster Tools. With WP, now the URLs of all my articles have changed. I have a sitemap.xml generator plugin, but because of how WP works, its address is http://mydomain.com/sitemap.xml WP doesn't use the www prefix, and when I tried to manually add it in in WP dashboard, WP locked me out and was trying to access http://.mydomain.com (with the dot in front) which obviously didn't return anything. Ok, so my question is, Google Webmaster Tools allows you to specify the location of your sitemap.xml file, but it forces you to use the www prefix. Since my sitemap file doesn't have the www prefix now that i'm on WP, how do I tell Google Webmaster Tools where it is? Intuitively I would think it wouldn't matter whether or not you used the www, but if I got to mydomain.com/sitemap.xml, I see a nicely formatted sitemap, and if I go to www.mydomain.com/sitemap.xml, I see a fucked up txt looking document. Question part 2: why is there a difference? Aren't www.mydomain.com/sitemap.xml and mydomain.com/sitemap.xml the same location??
