Twitter cards not showing



Some of my twitter cards are not showing up.

For some posts, e.g. the below
they are showing fine.

But for most, e.g. the below,

I get the following error when I try to validate using the card validator:
ERROR: Invalid value (message: Field description failed to validate because: text expects tag property, but not found in Map().)

I’m using the yoast seo plugin.

Any ideas what could be causing this error or what I could do to fix it?

Thank you


The first page you link to contains a twitter:description property, but the second one does not. You need to ensure that a twitter:description tag appears in your page.


Thank you for the reply. Not sure why its showing for only some posts… I’ll try asking yoast seo plugin support. Thanks again for the reply.
