Facebook error: Object cannot be liked -- WHAT IS THIS?

[Harvey cleo Reyes]

It says "Unable to like this object because it is not accessible (it may have been removed or you may no longer have permission to see it)."

I don't understand how it's not "accessible". All I did was comment on a link.
Here's the link:

^I have 9 likes and 3 comments on my post. They only appear on the link.

Here's how it looks like in my Facebook profile:

^I don't see the likes nor the comments and when I try to like/comment from my Facebook profile, the error message pops up.

This started happening a little over a week. Before, I could still see the likes and the comments on my post from that site.
