Said another way, (I am pasting description of problem posted elsewhere)
I have a sitemap on the root of my website (pixelpointgraphics.com) to help with my Google searches. The sitemap is sitemap.xml and is generated by a WordPress Plugin called Google XML Sitemaps
I was checking Google Webmaster tools to see if, indeed , the site map was showing up. When I click on their button to show the sitemap, I get an error message instead of seeing the actual sitemap. This makes me think that Google's bots may not properly index this site.
The url for the link from Google is: http://www.pixelpointgraphics.com/sitemap.xml
Click on that link and you will see the same error message that I get if I click on that link in Google's Webmaster Tools program.
Now, I notice that whenever I hover on any page for my site including the index page (home) I get this link:
http://pixelpointgraphics.com/ The www. stripped out. So try clicking on http://pixelpointgraphics.com/sitemap.xml
You will see the correct link and the sitemap file.
If I type http://www.pixelpointgraphics.com/sitemap.xml into a browser or if you click on this link you will sometimes see
the www. stripped away and the page will be correctly displayed. Sometimes it is not stripped and the error will occur.
If I type in ANY other url to the site (graphics or framing or..) then the www is always stripped and the proper page always displays. The problem only occurs if the link is http://www.pixelpointgraphics.com/sitemap.xml which has been described is the link that is created by Google on their webmaster Tools Site.
I am very interested in your thoughts!
