Problem with the cards



I want the twitter cards in my blog but I have a lot of problems, and I can’t solve.

When I test the domain I have this log
INFO: Page fetched successfully
INFO: 14 metatags were found
INFO: twitter:card = summary tag found
ERROR: Required meta tag missing (twitter:title)
WARN: Not whitelisted

And when I test a post hte first that I see is
Unable to render Card preview
INFO: Page fetched successfully
INFO: 4 metatags were found
WARN: Not whitelisted

Please help me to solve the problem with the domain and how can I go to the white list.

The domain is my user is @MemoriasMundo.

Thanks a lot in advance .-


Looking at your site, you’ve got this:

<meta content='' name='twitter:title'/>

that’s a blank title value, which isn’t allowed.
