I am trying to validate my web site for Twitter cards but I get the “Reason: is not a valid screen name” error. When I tweak the DOM to make the field writable, I get the error “Reason: The site user provided doesn’t match the one in your existing whitelist entry”.
I believe this is because I previously validated the domain using a Twitter account that I have since deleted. Is it possible to get this fixed so that I can start over? The domain name is josheinstein.com.
