Twitter Card Error: No Card Found (Card Error)

[TrueCompetitors]

I installed the yoast seo plugin and am receiving the following error on the card validator site:

Log
INFO: Page fetched successfully
INFO: 5 metatags were found
ERROR: No card found (Card error)

Any tips out there? Our site is www.truecompetitors.org
