On Twitter, I can't show an image card when tweeting my website https://startcrowd.club But it works perfectly on Facebook.
I want to show this card: http://startcrowd.club/images/startcrowdimage.jpg
I tried https://cards-dev.twitter.com/validator and I got:
INFO: Page fetched successfully
INFO: 9 metatags were found
ERROR: No card found (Card error)
The relevant metatags on my page https://startcrowd.club/index.html are:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<meta property="og:image" content="images/startcrowdimage.jpg">
The documentation I followed is:
Add:
<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:image" content="https://startcrowd.club/images/startcrowdimage.jpg">
