Wordpress sitemap help please with plugin

Hi,

I have posted a thread at the Wordpress support forum but no answer there:

WordPress › Support » [Plugin: WordPress SEO by Yoast] Google says the sitemap file is html and has er


So hoping some technical experts here might be able to help.

I have the latest version of Wordpress installed (still setting up at moment) and trying to get the Wordpress SEO plugin by Yoast working. It seems a great SEO plugin but is giving me this error at Google Webmaster tools with the generated sitemap.


I have installed the latest version of the plugin and generated the sitemap and submitted the url to Google.

I get the following error inside Google webmaster tools:

Sitemap is HTML
Your Sitemap appears to be an HTML page. Please use a supported sitemap format instead. Problem detected on: Apr 13, 2011

The sitemap is located at:

http://www.dalereardon.com/internet-...ng/sitemap.xml

Is it a plugin bug or have I set things up incorrectly?

The plugin I am using is at:

WordPress Plugins - Free & Reliable - Yoast


If you can't help with this plugin can you recommend a good sitemap plugin?


Thanks,

Dale.
