I tried Twitter validator on my site desimedicos.com and tried various links to pages like http://desimedicos.com/understanding-normalisation-neet-medical-entrance-exams/ but it says "Fetching the page failed due to an internal error. I have used wordpress yoast plugin to enable Twitter cards on my site Twitter username @desimedicos. Is there any solution to this?
Apologies for that. Think it’s back up. Mind trying again?
Not working for me. I get the internal error as well.
