Twitter Card: WARN: Not whitelisted



I just created my first twitter card. I have a site:

Twitter validates everything but give me the Not whitelisted error. How can i fix this?


Just checked your page, and I don’t see any twitter:card markup inside your <head> tags. That is required in order for the validator to work, and for Cards to render.


This threw me at first too.

The validator says WARN: Not whitelisted when it should probably say WARN: Missing twitter:card meta tag


Yes, I agree that we could significantly improve the validator error messages, but that has not been a high priority. Thanks for the feedback!


Thanks Andy. I just felt bad for you answering the same question over and over! (I think there are at least 3 in the last week on this developer forum!)! :smiley:
