Hi Yannick,
I think there might be an issue with generating og:image for articles built in Yootheme Pro. So I tried to make a Structured data rule for Custom image, all pages.
I did the following which does not work:
Under the What to do tab (3)
Structured data type > Article
Image > Custom value (and selected the image).
Everything else is set to Automatic.
This is the website: https://www.[redacted].se/
This is the custom image I've set in the rule: /images/opengraph/advokat-annakarin-sorman-1000px.jpg
I've attached this image here too just in case.
What might I have done wrong, please?
