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:
https://www.magensa.net/metatest/card-readers.html
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?
