I'm using the free version. What does this mean:
"This XML file does not appear to have any style information associated with it. The document tree is shown below."

It came up at the top of the page after I clicked on the link you gave to test if the sitemap was showing up in my website folder. My website is hosted on MobileMe.

Will the sitemap still work for the search engines and will the message stay there and be seen?

All the pages seem to be in the sitemap list.

Thanks.
Hello,

xml sitemap can optionally contain the stylesheet, that allows it to be nicely formatted in browser. This is *not* needed for search engines since they ignore style information, but is nice to have if you check it on your own. Standalone generator (https://www.xml-sitemaps.com/standalone-google-sitemap-generator.html) includes styles in sitemap, for instance: https://www.xml-sitemaps.com/sitemap.xml
Thank you.
