Twitter card

Hi,

I had twitter cards working but now when I tweet any post, it isn’t working.

My meta tags are below but don’t work.

<meta name=”twitter:card” content=”summary”>
<meta name=”twitter:url” content=”https://rucktales.com/”&gt;
<meta name=”twitter:domain” content=”Rucktales”>
<meta name=”twitter:site” content=”@rucktales”>
<meta name=”twitter:title” content=”Tales, opinion and comments from the Wold of Rugby Union”>
<meta name=”og:description” content=”Tales, opinion and comments from the World of Rugby Union”>
