When pasting in editor, the link is just plain text. If I choose Media, and Paste from URL address and fill in the link, it pastes into the post as colored link that can be clicked. Still, no video though.

No need to send you the particular video, since the problem relates to all YouTube videos.
Again, Vimeo videos and Twitter links work normally, only YouTube links don’t.

I tried disabling all plugins, but the problem still persists.

Thank you for your response, chienyi.
Yes, I tried. Normally it should show how the video would look like on the page, but now it only pastes as the URL.

Here you can see the difference between how embeding worked before (10 days ago) on the first picture, and how it works now on the second picture.

There are no spaces or characters around the link. I tried to use Twitter or Vimeo links in posts, but they appear. Only YouTube for whatever reason doesn’t work.

Edit: Instead of copying only the link, I tried to copy and paste this code found under YouTube video, and “Share”. There is for example this code:
<iframe width="560" height="315" src="https://www.youtube.com/embed/6cpRuF4su1U" frameborder="0" allowfullscreen></iframe>
It does work, but it still bothers me, that I can’t post videos the same way like before.

Thank you for your answer, bdbrown.
It is interesting.. I tried disabling all plugins, but the problem still persists.
If you go to this website, under “NOVá VIDEA Z GAMERS TV” on the left side, do you see any video, or just the link?
