Hello. I have a problem with a card validation (https://www.screencast.com/t/rgtQlLuV). I get the following messages: “Unable to render Card preview” and WARN: Not whitelisted. Is there a solution to this problem? Here’s the link to the page where I added meta tags: http://snaptest-siteb-6.us-west-2.elasticbeanstalk.com/tx01
There are no meta tags related to cards in that page. Please review the pinned troubleshooting post carefully.
Thanks, I rewrote the logic of the meta tags delivery and got an “approve”. But the page which received this “approve” doesn’t show the card. http://snaptest-siteb-6.us-west-2.elasticbeanstalk.com/tx01
I am trying to set up twitter cards and am getting the same problem.
I used the code at this website for Large Image cards: http://www.superwebtricks.com/twitter-summary-cards-for-blogger-blogs/amp/
Obviously changing the relevant bits where told. Is there a problem with this code?
My blog is at www.theglobalobsession.com.
Okay, I tried some other code and now it works if I go to my blog’s main page at http://www.theglobalobsession.com. But individual posts don’t work - for example when I put in http://www.theglobalobsession.com/2017/01/djibouti.html the log says
INFO: Page fetched successfully
INFO: 18 metatags were found
INFO: twitter:card = summary_large_image tag found
ERROR: Required meta tag missing (twitter:text:description)
How do I fix this?
I’m not an expert at using HTML. You may already have gathered…
Okay, so now I tried the instructions here:
Now the cards work for individual posts but not for the standalone domain (basically the opposite of what I achieved in the previous post).
Why can’t I find a solution that works for both the domain and the sub-pages? Any ideas?
It is difficult for us to directly support Blogger configurations as they depend on knowledge of setting up conditional code in Blogger templates. This other thread has a solution that seems to be working for some people.
