Site map error

[maureenmclean]

I have submitted a new site to Google and have received this warning on all my pages about my site map,  Google did not list the site. I am new to site maps etc and do not understand what it means and what I should do about it.

Paths don't match
We've detected that you submitted your Sitemap using a URL path that includes the www prefix (for instance, [external links are visible to admins only]). However, the URLs listed inside your Sitemap don't use the www prefix (for instance, [external links are visible to admins only]).

Any advice would be greatly appreciated
Thank you
Maureen

Hello,

as it says in details, you should create a new site entry with www in domain name (or without www if current one is www.domain.com)
