I've searched for this but get no joy. I've got Facebook Page Publish 0.3.9 and I'm setting up the options.
I've created my app and step 1: Facebook Connection: Reports access granted and fields show green
Step 2: Publishing: returns this error...
Facebook returned an error: Invalid user or page ID. Please refer to the detailed setup instructions. [Error occured at line 1078] Your connection options could not be validated.
The help says "Click on one of the displayed user profile or page names or enter your profile or page ID manually." Except it does not display any user or page IDs, and when I manually enter either my user ID or the ID of a fan page I administer it returns the error above.
Any clues would be appreciated.
