prsdavis3 on "[Plugin: WordPress SEO by Yoast] Error on Page-Sitemap.xml"

WordPress version: WordPress 3.5.1
WordPress SEO version: 1.4.7

I did this: Installed the newest version on your plugin.

I expected the plugin to do this: I expected it to automatically generate an XML sitemap.

Instead, I'm getting the following error:

This page contains the following errors:

error on line 11 at column 60: EntityRef: expecting ';'

Below is a rendering of the page up to the first error.

Thanks in advance!
