Unable to render Card preview


I just recently tested everything for twitter cards.

here is the log
INFO: Page fetched successfully
INFO: 53 metatags were found
INFO: twitter:card = player tag found
WARN: Not whitelisted

because my website is not yet whitelisted, it cannot display the card? not even for testing purpose?

URL for card validation


Player cards need to be whitelisted before they will be shown on Twitter itself. I’m not sure why your Card preview is not displaying.


Alright, could be some minor issue with the service?
