Hi Yoast & Co.,
I also have the version 1.4.7 and some trouble with table press plugin http://screencast.com/t/WUZ0s8a3p
I deleted the Yoast SEO plugin, deleted files and then reinstalled the plugin. Activated the plugin. But the problem is even there.
It seems to be that WordPress-SEO-Plugin takes the "Custom Post
Type" of TablePress into the Sitemap even it isn't "public". That was the answer from Tobias Bäthge (Developer of the TablePress Plugin).
You can see the problem if you click on any sitemap following: http://www.sportwettenbonus.com/sitemap_index.xml
