How do I get my twitter card



I am trying to get my Twitter Card to work and I received an email with the subject line “Your Twitter card is ready!” and says in the email that a summary has been activated for my website/blog ( however I don’t see my Twitter card on my Tweets nor a link so I can tweet my Twitter card.

I don’t know if I did something wrong - when I validated the code, all of the bullet points were green except for twitter:domain (message: “required meta tag missing”) and twitter:creator (message: invalid screen name) but even when I manually put the information into these fields I still get the same error messages.

What can I do to solve this problem?
