Why did the videos disappear

[wbport]

I had had my own website until about a year ago, but am asking this question as a visitor to a specific site. When I visited this site quite a few months ago, there were a number of youtube videos on it to illustrate various examples, but now there is space for the videos but nothing appears. When I displayed the source code for the site, I found this where I expected a video:

<figure class="wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-4-3 wp-has-aspect-ratio">
<div class="wp-block-embed__wrapper"><a href="https://www.youtube.com/watch?v=JtKAScORevQ" rel="nofollow">https://www.youtube.com/watch?v=JtKAScORevQ</a></div>
</figure>

Can this be fixed by changing a browser setting? TIA

No. The administrator blocked you off to that site you were once on. Class files were used. Those are java scripts they used to accomplish this. Some thing like how they use javascript to ban a forum goer. Same thing. Not actually class files. They use a link to redirect your videos and put a blank there. They add a link to the page. But the layout of the link is different.

Have you ever used imageBam.com on any website blog? They add a link to add your pictures to the website. Where as before only text to be added to the text area. Now, you can see pictures or gifs to it. The link is attached to the page you were on. Sent back to you. HTML will work even with out the imageBam, because it's how the computer functions. A server is used to see your pictures on the website.
