Hi,
I am having the same problem. My error message is…
‘Invalid redirect_uri: De opgegeven URL wordt niet toegestaan door de configuratie van de applicatie.’
I have copied the ID and Secret from the FB app. This seems quite simple so I think it must be the URL..
I am using
https://pphdash.info/wp-admin/tools.php?page=add-link-to-facebook/add-link-to-facebook.php.
I have tried lots of url combinations as the one above seems too long but I think this is whats meant in the FAQ
Hopefully someone can help
