web site link wrong!

The link web site doesn’t work.
If you see the code you’ll see a sintax error.

The error is also in your example.

Here
https://www.wpembedfb.com/demo-site/custom-embeds/page-embed/#more-17
The href propriety is “https://https://www.wpembedfb.com”, you can see that this is not correct!

Can you solve this problem, or tell me how can I hidden the link?
Thanks
