Info is missing while sharing on FB

I’m pretty much satisfied with this great plugin. Thank you for this amazing plugin.

Recently I’ve started facing problem, that I can’t see any link, thumbnail image, title, description while sharing on FB.

The problem wasn’t there before. For ex:

This link has the problem: https://www.indiavirtualinfo.com/blog/best-adventure-activities-north-india/

But this link doesn’t have: https://www.indiavirtualinfo.com/blog/5-popular-treks-uttarakhand/

How come it be possible, that one link has the problem but the other links don’t?

I tried to check it from here: https://developers.facebook.com/tools/debug/

But it says, the properties are missing. What’s the solution please?
