I have gone through the troubleshooting steps. However, I cannot run “curl”.

The error looks very specific, what is the twitter:description tag set to?

[cono_sur]

I’m using the Open Graph (i.e. og:description) tag.

<meta content='Wine review of 2016 Goats do Roam Red from WO Western Cape, South Africa. This easy drinking red has generous aromas that are soft with plummy, peppery and red cherry notes, along with some meaty and vanillan oak nuances...' name='description' property='og:description'/>

The value will not be detected as you’re using both name and description fields in the same tag.

Hrmmm… you’re right. I removed the ‘name’ attribute and it works now. Thank you!

Now to see if I can keep it this way without any negative effects.
