I don’t understand. how I can enable my visitors to embed my blog post on their website?

Thanks for the suggestion, James Huff!
I have tried this but nothing changed. I am still facing the same error. ??

The error says that the problem lies with the wp-include/post.php file, What that means?
what does this file do?

I am facing the same warnings and my website is broken badly.
@robrecord Can you please guide how I can recover my website.
