When trying to validate (Domain error), everything seems fine, just need whitelisting but then I get this message which does not help a lot:
*.la-cascade.ghost.io whitelist request failed
ERROR: Card validation failed
Can you help me please? Thanks!
Hi Pierre, I’ve just run that through the validator and it goes through OK, with a button to apply for whitelisting approval on the left-hand side. If you run the validation again and request approval, you should be all set as far as I can tell.

Hi Andy, thanks for your kind answer. I ran it again and, nope, same answer.
Since this was a post, I tried the same with the home page of the blog, same problem. The validator says it’s ok, I apply for whitelisting approval on the left-hand side, answer the questions (the only thing I modify is ‘description’, which is blank, the rest is already filled-in), send the request and boom, error message.
Am I missing something? Thx again, p

Hi
I’m currently having the same issue validating some of my brands
INFO: Page fetched successfully
INFO: 31 metatags were found
INFO: twitter:card = SUMMARY tag found
WARN: Not whitelisted
I’ve tried to verify a product page and this summary page (http://www.scottsofstow.co.uk) but it always comes back with the same error…
*.scottsofstow.co.uk whitelist request failed
ERROR: Card validation failed
Any ideas?

Did anything every come of this? Having same problems trying to get whitelisted.

I am seeing the similar issue with http://app.guidedeverses.com. Screenshot below. How can I resolve?
As the validator is showing you, the twitter:card tag does not contain a valid value. It needs to be one of the supported types.
