Summary Large image Card working for main site, but not for articles


Getting a WARN: Not Whitelisted error for article URLs on my site. Using the card validator for works and says it’s whitelisted, displays as it should, but trying to validate for does not work and gives me the whitelisted warning.

Went through the forums here and couldn’t find anything that worked. Here are the meta tags being used on the article page:

<meta name="twitter:card" content="summary_large_image"/>
<meta name="twitter:description" content="With this WordPress plugin, you get a link to edit any page/post/custom post type from any page on your site directly in the admin bar."/>
<meta name="twitter:title" content="Admin Bar Edit Content Links WordPress Plugin - Brett Shumaker"/>
<meta name="twitter:site" content="@bshumaker"/>
<meta name="twitter:domain" content="Brett Shumaker"/>
<meta name="twitter:image" content=""/>
<meta name="twitter:creator" content="@bshumaker"/>

Am I doing something wrong?
