***Update: Issue is resolved on 17/Feb/2017***
Are you trying to validate your domain for Rich Pins on Pinterest? It is actually a very simple process with just 2 steps involved.
As you know, a Rich Pin shows extra details on the pin itself.

Rich Pin Validator
When you go to the Pinterest Rich Pin Validator, you can see the below steps.
Just enter any of your blog post’s URL (not your home page URL) into the box and click validate to get the pin validated.

The Error
But Pinterest is throwing an odd error from the past 2 weeks when using the Rich Pin Validator: ‘Something went wrong at our end’.
For example I typed in a URL – “http://glorioussunrise.com/amusing-tales-globe-trotting-vegetarians/” and clicked the Validate button.
The URL was successfully validated with the message shown as “Your Pin’s have been validated. Apply to enable Rich Pins”.
Then I typed my domain URL to apply for Rich Pins, then got this error.
Error details
If you notice the details, it shows a red mark for ‘Authors’ details even though all the details are available for my post.
Then I looked up online to see how to get this solved. And I found that many others are also facing this issue. I submitted a request to Pinterest to look into this. They acknowledged this error as a bug and are working on it.
Status: Resolved as of 17/Feb/2017
I will update this post with the solution when I get a reply. (Update: The issue has been fixed by Pinterest developers :))
Pinterest replied saying that they are still working on it.
So, bookmark this page and check back later for updates.
I hope this gets resolved asap. Will talk to you soon.
UPDATE:
ISSUE is RESOLVED by Pinterest developers. It should work now even though the red mark is still shown for authors tag.

So glad that it is resolved 🙂
Keep Pinteresting!

This happened to me and it’s still going on here on March 18. Any idea as to why it’s fixed for some and not others?
Hey Max, seems like Pinterest is very glitchy lately. May be it would get resolved in a few days. In any case, try contacting their tech support.
Still not resolved as of April 2, 2018 just keeping you guys posted on the update 🙂
Hi Alex, thanks for the update 🙂 Apparently, Pinterest keeps having this glitch. Hopefully it will find a permanent fix soon!
