I have 2 sites using WordPress 3.8.1 -one using the latest WP SEO plugin, the other one using 1.4.24. My site’s sitemap with 1.4.24 is fine and working. My new site using this new plugin is working too according to Google Webmaster Tools (everything is indexed) however when I open the sitemap URL I can only see white page displaying only my sitemaps URL… I asked Synthesis support about this and they told me sitemap is Ok, the only problem is W3 Total Cache + Yoast Updated Version. Seems that having them both have page display issue with Yoast Sitemap.
I think I will wait for the solution of this. At least everything is indexing for now
