Hi, Iâve been trying to set up Twitter Cards but keep getting an Invalid Card Type when trying to validate and Apply.
Iâm using WP SEO by Yoast and have activated the Twitter Cards in the social settings.
Iâve filled in all the required fields for the summary cards and every time I try to validate iâm told âinvalid card typeâ. I get a preview on the Try Cards tab but when try to validate the preview isnât displayed, just the message âunable to render card previewâ.
Can anyone offer any advice please?

Did you figure out what was wrong? Iâm having a similar issue
Hi guys sorry for delay in my reply but as I wasnât getting help here I unsubscribed from thread.
I now have them working. Go to the twitter cards again and select standard summary card, enter the details from one of your blog posts, filling the required fields.
When you go to validate and apply use the blog post URL and once validated youâll see a link to valid your home page, click that.
It worked for me and I was approved within minutes after wards. 
Sorry, replied below you comment. Pop back for how i resolved the issue with Twitter cards 
I have and left a reply at bottom of thread.

@barry_wells,
thanks for following up, and glad you got it working! (And thanks for helping others!)
Hi, I was able to use twitter cards yesterday but its not working today. I get a âcard type not foundâ error when I try to validate. please help.
Was having the same problem and it was sorted when I added the blog post URL not the general website URLâŚThanks for the help!

Thanks for that update, @taranofal!
I had some headaches getting this to work too. My site was in âcoming soonâ mode. I set it to âLiveâ temporarily and all was well. Itâs possible that the error was showing up because the Vailidator was not seeing the correct URL when it checked my site.
Thank you @barry_wellsâŚyour method worked perfectly.
Thanks a lot, adding any postâs link in the validate url field did the trick for me.
