Galleries not showing / Page broken

send me the url of the page where the shortcode is used. I’ll check

https://fortunelake.org/about/photo-albums/

Hi,
Try putting the default app id/secret

id:
177197009081544
secret:
64a6d7830db5893985cbe0475ce5a9db

Ok. That worked. Is there something incorrect in the Facebook app I created for the page?

No your app is ok.
Just that facebook gives slightly different data format for the newly created app id/secret.
I’ve already fixed that on the development version. You’ll be able to use your own key from the next version.
