ERROR: Internal error (Card error)


#1

Hi,

I searched a lot on the internet and I found no solution to get my card displayed.

This is an example tweet https://twitter.com/ppscslv/status/848307416689258496

that via https://cards-dev.twitter.com/validator

shows in that way:

The file (png) can be accessed via public internet, there are no restrictions.

Can somebody give me some help please?

Thank in advance!
