Go back to your webpage and particularly on your blog post.

You'll need to be logged in Wordpress as an Admin and then click Edit post at the top bar WP menu on the page.

When the editor loads up, you'll need to toggle your view to "Text" (HTML-based) editor instead of the "Visual" one.

(P.S. I noticed with the recent update to WP 5.0, this "Text" editor seem to have disappeared. After much digging it turns out you can get it back by adding the Classic Editor plugin.)

Now, when you're on the "Text" (HTML-based) editor, paste in the first part of the code at the very beginning.

And then wherever you want, you can paste the second part of the code as well.

When you've done all that, click Update. And that's it!

Make sure to view your post on your actual site to make sure it's displaying properly and working.

You won't actually see the FB Like & Share buttons in the WordPress Visual editor. You'll need to head out into your blog post page to view it.

And there you have it folks! I hope this has been informative for you and thanks for taking my course.I hereby pronounce you as FB Like & Share certified! Hehehe!

Cheers!
