I’ve used twitter cards before thru a plugin in Wordpress, but not coding them.
I’ve created this code, and put it on the header section, but the twitter card validator displays this error: “Unable to render Card preview”
Here is the code:
<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:site" content="@bpmsupreme">
<meta name="twitter:title" content="Win a DJ Set Up Worth Over $6,000">
<meta name="twitter:description" content="Delivered Just in Time for the Holidays. Win a Pioneer DJM 900 NXS2, 2x CDJs 2000NXS2, a full year BPM Supreme Membership, and a full djay PRO software license. Enter to win now!">

Am I doing something wrong?
