URL path

First to greet the entire community and move to explain the problem, the fact is that the sitemap my Web makes it automatically vbseo sitemap generator to google and yahoo, but when I will see in webmaster tools to give me the following failure

The routes do not match.
We noticed that you submitted your Sitemap with a URL path that does not include the www prefix (for example, ejemplo.com). However, the URLs listed in your Sitemap them using the www prefix (for example, ejemplo.com).

would know that the please and how to fix it?

thanks in advance.

I'm not an expert on this, but it looks like you have registered your site as ejemplo.com with google but are submitting ejemplo.com URLs. Double check that you include the www when you list the site in google's webmaster tools.

Your vBulletin setting must have www in the forum domain.

Whether you want the www or non-www version of your site, you will need to select and use only 1.
