@john-komatsoulis That’s weird. I was about to say it is something in the CSS, but then I realized we are using the same theme and I just published a YouTube video in my latest post with no issues.

The only thing I notice that is different is that I am using the iframe code and you are using something else. You might have the “Use old embed code” checked when you go to the embed code on YouTube. It should look like this:

Let me know if using the iframe code works better!

@john-komatsoulis How about your media settings? Do you have a max width set there? It’s under Settings > Media.

I did deactivate Jetpack and that solved the issue, just hope it’s not a temporary fix.

Thanks for taking your time to find this forum post, you rock !!
