Valid cards give error

[lessonpix]

I have just tried to switch from Summary (which was working) to Summary With Large Image. The validator says the cards are fine and I submitted for approval.

Here is a sample URL: http://lessonpix.com/materials/383707/initial+s+minimal+pairs+Puzzle+Cards

I got back an email saying:

“The URL you provided for lessonpix.com to use the summary_large_image card did not validate. Please make sure the page contains valid metadata, then reapply for a Twitter card.
Thanks for your patience. See you soon!”

But it does validate! The only thing that I changed was the card type (from summary to summary_large_image). And all the check-boxes in the validator are green.

What’s up?

It could be the image tag. For Summary with Large Image, the key value is “twitter:image:src” not “twitter:image.” Resubmit giving that a try.
