Posting videos

Hi, from today I have problem with posting videos, I tried everything and still it will appear only as link. What changed?

You mean like this?

This is what I get if I use the link from the youtube “share”

This is what I get if I use the URL of the youtube page itself.
(I put in underscores (
) so the link above would not render.)

From your recent posts, it looks like this is one of the links you mean:

If so, it is because of the s in https://.  Delete the s so it is just http://, and it will embed:

Thank you very much Yossarian, I had no idea that S can be problem.
