Black Bars on embedded vimeo video

Hello,

Can you please share the URL of your site.

Thank you for your reply.
Here is the url to the post where i embedded the video
https://cristipaltin.ro/milena-si-alexandru/

I manage to fix it myself.
First i tried to paste the iframe into the visual tab of the post and did not work, so i posted the link of the video. The result was the video with black bars on top and bottom.
To fix it i changed the post to text tab and paste the iframe. Now the video shows like it supposed to.
@poonam9 Thank you for your intention to help!
