Dexterity content type video not working

I have a dexterity content type video, where I would like to view a demo video using the youtube URL. I am revisiting the page after a year. It used to work when I set it up. It is not working now. The yourtube URL is working independently. What could be the potential issue.

There is no video or iframe tag inside your demo page. Check the HTML filtering settings of Plone.


Thanks. I was using an addon Wildcard media. I upgraded to the latest version and that did the trick. issue resolved now.
