Wistia videos once was in the yoast video sitemap, but no longer appears.
Everything is indexed but Wistia videos. They have been indexed before and I had richsnippets in SERP: http://screencast.com/t/gnfqHoJb. Here is an example of a page that has Wistia video: http://iloebesko.dk/inov8-trailroc-245/
Changes I made:
Since it had worked till not working I have in the meanwhile installed W3 Total Cache. I read many comment strings about problems with W3 Total Cache, but noone mentions my problem. I tried to deactivate W3TC without any changes.
Everything seems to be in the sitemaps but Wistia videos.
Am I doing anything wrong?
What is the solution?
I am extremely thankful for your support
