Twitter Cards: "No card found (Card Error)"

Ensure that the og:type tag is set. On Facebook it is not required, Facebook will use website as the og:type if it is not found. That is why it worked fine on Facebook.

By adding <meta property="og:type" content="website"> if the twitter:card property is not set, twitter will use summary.

So just add <meta property="og:type" content="website"> and I think it will work fine.

PS: I also had the same issue but when I added <meta property="og:type" content="website"> it worked for me.

Add:

<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:image" content="https://startcrowd.club/images/startcrowdimage.jpg">
