Hi all, I’m trying to validate one url, but the response is always the same:
Unable to render Card preview.
ERROR: Internal server error
Anyone can help me, please? The url is: http://www.educa.net/curso/curso-practico-de-aprovisionamiento-y-mantenimiento-del-almacen/
I added all meta tags properly, but I don’t know what is happening.
One question more, I think this validator process is not necessary, right? Because few of my tweets display cards properly, without have made the validation…but the problem is that I just made a new tweet, and the card it is not being displayed.
If the validation is necessary, it would be fantastic some automatic mechanism…
