We are currently in the testing Phase of a Site; the Domain is Testing.thenameofourcampaign.com
It is password protected. Our Production URL (minus the Testing.) will also be password protected until launch.
Could the password protection be what is causing the error “Invalid Card Type”?
Are there any special protocols we need to take into account when applying for Twitter Cards on a password protected site?
Is there a way to expedite the process?
