Twitter ERROR: No card found

Hello!

I found that the minification by WP Fastest Cache failed to parse correctly. With that, the HTML markup of that page is also incorrect. Now, although browsers can cope with many errors, Twitter is less capable.

So, I suggest flushing that page’s cache, and try debugging it again.

Thanks, I found the cause of the problem, it was an Autoptimize plugin, after it is turned off everything works fine, I will try other settings.

All the fault was this setting: Inline all CSS?

“Inline all CSS” indeed pushes social meta-tags (or whatever they’re called) down the HTML and the applications reading the HTML only read the top part. In general “inline & defer” is the better approach (see AO FAQ for more info) but you can alternatively also force AO to inject the CSS later in the HTML, e.g. with this code snippet;

add_filter('autoptimize_filter_css_replacetag','alexms_css_replacetag',10,1);
function alexms_css_replacetag($replacetag) {
	return array("</head>","before");
	}

hope this helps,
