URL validated properly and site whitelisted but does not appear in the twitter timeline as a Twitter Card

[juanat_robles]

My site has been accepted for the summary image large twitter cards.

I tried different URLs and most of them work, for example:

http://app.fanraisingapp.com/cards/lol3.php

Unfortunately this does not work:

http://app.fanraisingapp.com/fantweet/ven-a-la-prueba-de-sonido-de-love-of-lesbian/

it is validated properly but not displayed as a Twitter Card in the timeline.

Any suggestion?
