I'm getting both errors. The App ID and App Secret is correct. I don't have any problems with Facebook Page Publish for any other sites... Except this one. Getting two errors:
Facebook returned an unexpected dataset. Try to resolve this issue, update the plugin or inform the author about the problem.
[Error occured at line 597]
Your application's access permissions could not be granted.
Some or all access permissions are missing. Please click the button Grant access rights! and authorize the plugin to post to your Facebook profile or page.
[Error occured at line 774]
Your page or profile's access permissions could not be verified.
I already made the standard line 774 correction as shown in previous threads. It worked fine (had to grant access every time I logged in to WP dashboard and made new post - but it worked). Then all of a sudden for no reason it stopped working..
Anybody got a solution to this? My line 597 is:
throw new FacebookUnexpectedDataException();
