we have the same problem here how we can fix this
twitter:card markup is in your page source?
I’m unable to access the URL (the page that comes back just shows a “60%” bar), but I would double-check that you have all the required tags for implementing Twitter cards in your source code, and then also make sure that your site loads and is accessible to our web crawler (Twitterbot).
I’m having the same problem when I try to validate a link on my friend’s blog (mine works fine, though).
Please provide us with a link to a example post, the link in your screenshot is not fully readable and I don’t want to type it manually from the screenshot, thanks!
That page has not Twitter Card Meta-Tags at all, it seems.
@cintiamcr there are no Twitter Cards tags on that page, so until you have that working, you won’t be able to validate the page.
i fix the problem thanks for you help
