I have the "Add both a YouTube and an Easy YouTube-link." option enabled, but they're not showing up. Even if I use "Add YouTube-link." I don't see any extra link. Video loads fine though.
I would link you, but I was testing this locally, but I can tell you that while the iframe shows up, nothing in it or after it shows links in the code.
It's a great feature especially since I would really like to make the site accessible, props for adding it.
Other options don't seem to be working for me either. No matter what size player I choose, it's still the same size and it won't Center for me.
