Some cards validate and others don't validate


#1

I am having an issue with my Twitter Cards. It seems that some blog posts validate just fine with a card, while others get a “No card found” error.

Examples of Errors:

Example of valid card:

Any ideas on what is going on here? Why do some work, and not others?

All three cards validate just fine for me.

Yeah, for some reason, the next day they started working just fine. So, I’m not sure what the issue was.
