Posts appear but links are broken

Hi there,

My posts appear on my posts page as previews just fine. But when I click them, they are all broken links!

soholanguagegroup.com
soholanguagegroup.com/blog
– Both work fine

https://www.soholanguagegroup.com/’/2016/07/10/the-penultimate/’
https://www.soholanguagegroup.com/’/2016/07/10/the-letter-h-vs-the-french/’ ?
https://www.soholanguagegroup.com/’/2016/07/10/where-have-you-been/’
– None of these work. They get the error below:

When I click on a Post I get this in the error console: “Blocked a frame with origin “https://www.facebook.com” from accessing a frame with origin “https://www.soholanguagegroup.com”. The frame requesting access set “document.domain” to “facebook.com”, but the frame being accessed did not. Both must set “document.domain” to the same value to allow access.”

Does anyone have any idea what this might mean?

Thank you
