I've read a couple of previous posts on similar issues but they have either not resolved my problem or didn't explain fully how they resolved their's.
I have followed meticulously the blog instructions to install WPB and create a FB app. Well...I think I have. Some of the options have changed in FB since the instructions were written. However, I can get posts onto the app no problem (http://apps.facebook.com/finnbritplayers/), but they simply won't go the group page (http://www.facebook.com/group.php?gid=5986322313). The feed URL is http://www.finnbritplayers.com. I have entered both my personal FB ID and the group ID. I notice that there is no 'Grant permissions' to click on as stated, however, 'Checking permissions' seemed to do the same thing. It returns the following:
This page is where you can check and grant extended permissions, which enable WPBook to publish to your personal wall and/or to the walls of fan pages.
The Facebook profile ID you are currently logged in to Facebook as is [PERSONAL ID]. You have defined [PERSONAL ID] as your Facebook user id in WPBook Settings.
FB profile [PERSONAL ID] has granted these permissions:
Caught exception in getting permissions for user: Invalid OAuth access token signature.Error code: 190
Error posting is checked, but no errors are reported when publishing.
I'd really appreciate some suggestions :o)
