Unable to render card preview, no logs


I’m running this sample code snippet for a twitter card:

<meta name="twitter:card" content="summary_large_image"><!--as is-->
<meta name="twitter:site" content="@magtek"><!--as is-->
<meta name="twitter:title" content="MagTek Card Readers"><!-- CMS product group name + Static 'Support' -->
<meta name="twitter:description" content="Secure card acceptance for mobile and desktop devices"><!-- as is -->
<meta name="twitter:image" content="http://www.magensa.net/metatest/images/card-readers.jpg">

To test, I put this code snippet on this page:


But when I test that URL on the card validator, I get ‘Unable to render card preview’, and there are no error logs.

What’s going on?


This seems to work fine in the validator for me, can you confirm this is a current issue?
