Twitter Card Validator


I am implementing Twitter Photo Card on the site

I have used the sample code from this page: - but with my own content.

When I run the site through the validation I am getting a number of errors - mostly on fields that the documentation says are optional:

  1. twitter:domain
    Required meta tag missing

  2. twitter:site
    Invalid screen name

  3. twitter:creator
    Invalid screen name


Here are my meta tags:


What is the fastest way to validate and push through the approval of this site for Twitter Cards?

Thank you,
