Hello,
Using:
WordPress v4.8.1
Pro v1.1.1
Snippet v2.0.2
I have install and setup the Snippet a couple of weeks ago, I just test my site with the Google Web Tools, Structured Data Testing Tool to realized that the Snippet Extension is not working, as all the Data Item Tags are empty.
google Structured Data Testing Tool link:
https://www.google.com/webmasters/tools/testing-tools-links?hl=en&siteUrl=http://dmg-mg.com/
I have the option to enter this information manually, but if I do, what is the point of your Snippet Extension…
Please advice.
