When I try to run the twitter card validator on our website, we get “Internal Error Please Try Again.”
This error has been persisting for a month or so. The website in question I just tried to test is: http://www.selfiechallengeapp.com/selfie/6395889203544064/5750085036015616/
I was able to run your card through the validator and tweeting the given URL displayed the card correctly. Apologies for the intermittent error messages.
