I don't have the app namespace field either.
I am using WordPress 3.4.2 and Facebook plugin 1.1.8 as well.
I haven't been able to set up Social Publisher at all.
- There's a check by #1 "A Facebook application identifier associated with..."
- There's a link for #2 that I don't really want.
- Finally, there's #3 "Authenticate with Facebook to allow your Facebook application to post to your timeline or page on your behalf when a post is published."
The very next few lines/links don't help.
The first link "Associate your WordPress account..." gives me an error:
"API Error Code: 191
API Error Description: The specified URL is not owned by the application
Error Message: Invalid redirect_uri: Given URL is not allowed by the Application configuration."
Where do I address this redirect_uri problem?
The second link "Connect your Facebook account to get started." does nothing but change the URL to have "#facebook-login" appended at the end.
Is this supposed to do something?
