Summary Card - Validator : Warn : Not Whitelisted

[bedigitalcom]

Hi,
I read carefully the instructions to post twitter cards from my blog but I doesn’t work.
Validator warns “Not Whitelisted” though I added the required code in my head section, being :

<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:site" content="@bedigitalcom">
<meta name="twitter:creator" content="@bedigitalcom">

Have I done something wrong ? Any help welcome !
Thanks.

I forgot to mention my blog url : www.digitalcommunication.be
And the URL of the article I wanted to post on Twitter with a summary card with large image
http://digitalcommunication.be/article/gouvernance-2-0/
So you have all information I have.
Thanks again for your help!
