For me it was on /wp-admin/options-general.php?page=sfc in WordPress backend and then go to the section which says ?Publish Settings?. Click those buttons and follow the process.

If you still have troubles, delete your cookies and set up a new FB application. Then update the data in Simple Facebook Connect and re-apply the permissions.

Hope this helps!

@all
What worked for me was to simply put up a new Facebook application and update the corresponding data in the plugin page (App ID, Secret, Key).

Problem sovled!
I created a new application on Facebook and updated the settings in SFC. Then I had to grant Offline-Permission and Facebook-Permission again and now it all seems to be working.

But if anybody know a better way to fix this, you are welcome to let us know!

Same problem here!
It used to work and from one day to the other it’s not working anymore.
Have you found a solution?

Update!
The problem above could be solved by deleting all the cookies in my browser.
However, the posts still are not being published on Facebook automatically.
