[Plugin: WordPress SEO by Yoast] page-sitemap.xml

Hi, I’m running WordPress SEO 1.2.8.7 in a few sites and for some reason, page sitemap doesn’t show from here: https://www.impulsotecnologico.com/empresa-madrid/sitemap_index.xml. The site page is: Impulso Tecnologico running WP Version 3.4.2.

Thanks in advance.

Jose.

Hi I’m using WordPress 3.5.1 and Yoast 1.4.3 – small site, just a few pages using responsive theme with child https://www.calyenty.com
when I click the sitemap.xml I get the following:

Error loading stylesheet: A network error occurred loading an XSLT stylesheet:https://www.calyenty.com/wp-content/plugins/wordpress-seo/css/xml-sitemap-xsl.php

What do I need to do?
