Validator doesn't work


#1

the twitter cards validator (https://dev.twitter.com/docs/cards/validation/validator) doesn’t work for me.
It’s either unable to fetch my url (http://iretweeted.mina-grey.com) or keeps saying invalid card type.
Code, in case I’m doing something wrong:

<meta name="twitter:card" content="summary">
<meta name="twitter:site" content="@Retweetedi">
<meta name="twitter:title" content="iRetweeted!">
<meta name="twitter:description" content="See Who Retweeted, Say Thanks.">
<meta name="twitter:creator" content="@Sarasvati10">
<meta name="twitter:image:src" content="http://iretweeted.mina-grey.com/mysuperimage.png">

I am afraid it isn’t worth time. I’ve tried all types of cards, to no avail.
