Invalid Markup Twitter Card metas - solution (4 posts)

    Applied W3C valid standards syntax to +Twitter Cards. Valid by W3C and Twitter Cards Preview.

    <meta name=twitter:card value=summary> syntax changed to
    <meta property=twitter:card content=summary>

    * The issue was cased on non-standard name attribute values.
    * The Twitter Cards updated syntax had already corrected attribute value to content.

    twitter:url changed to og:url, since og:url is wide recognized Open Graph protocol standard.
    Added twitter:site to improve the snippet visual appearance.

    Please, could you include this fixed on the next release?

    Thank you

    I'm looking for kind of same info. I want to remove them from my site. Just only the twitter meatadata as w3c validator is marking them invalid.
    I tried unchecking the tick box but didn't work. :(

    Hello, is this why when I apply for a Twitter meta card it now says it is an "invalid card type"? See screenshot: http://d.pr/i/gKLU

    Did Twitter change their application process? I am using the Yoast plugin to set this up and when I apply for a card, it wants me to pick a card type. So I select "summary" (because I read that the plugin pulls "summary" as a default) and then when I enter the URL, it says it is an invalid card type. I tried it with other card types as well. Do you know if this is a problem with the Yoast plugin or something I could be doing to change this somewhere? Can you tell me what files to change and where? Thanks!

    @joycegrace :

    Having the same problem than you, asking the same question to the developers (and thanks for the plugin by the way).
