Summary Card - Validator : Warn : Not Whitelisted


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 !


I forgot to mention my blog url :
And the URL of the article I wanted to post on Twitter with a summary card with large image
So you have all information I have.
Thanks again for your help!


IT S NOW WORKING !!! No idea why as I didn’t do anything more to fix it. Anyway thanks for reading me.
