Hi

I’m using Education Hub. I pasted the link to my site on Facebook but the image is not showing up, so I can’t promote it as a result.

I have this issue: The ‘og:image’ property should be explicitly provided, even if a value can be inferred from other tags.

First, what does it mean?
Second, what can I do to fix this?

Please don’t overwhelm me with scripting jargon, just stick with layman’s terms!

Thanks!
