I think I am the only one I see with this problem. Not being familiar with FB apps, it took me a while to figure out what my specific problem was, but here's my best shot at describing it.
This is my personal FB I trying to post to, not a fan page or anything like that.
Plugin installs fine, followed instructions to setting up App in FB, everything went fine, seemingly. Went back to WPBook settings, and got to the "click here to grant WPBook the permission to publish to your stream."
Initially when I clicked this it brought up a window asking
"Allowing AppName access will let it pull your profile information, photos, your friends' info, and other content that it requires to work."
Naturally I click "allow"
And then I am presented with:
------------------------------------
This page is just for the author of the blog to grant extended permissions.
Your userid is XXXXX
You will need to enter that number into WPBook's settings page on your WordPress install.
Click here to trigger extended permissions dialog box
------------------------------------
I enter the id into the WPBook settings.
Then when I click "Click here to trigger extended permissions dialog box" I get a FB like modal window for Requesting Special Permissions that appears momentarily looking like it is attempting to load information into it and then I am redirected to a plain white page that is on my domain now, not FB, stating the same information above ^^^^
So, I try clicking "Click here to trigger extended permissions dialog box" again, and this time the Requesting Special Permissions window pops in again, but I am met with the following error message inside the box
---------------------
API Error Code: 100
API Error Description: Invalid parameter
Error Message: When enabling the profile selector, an app may not request user-only permissions
---------------------
My only option at this point is click "ok" and it redirects back to my public facing app page, which has blog posts it, so everything seems to be working accept for the stream business.
If I go to my app settings in my FB profile, I do see Additional Permissions, but the only option that is in there is "Publish recent activity (one line stories) to my wall"
If I enable "Show errors posting to Facebook Stream" in my WPBook options, I of course get "Caught exception: The user hasn't authorized the application to perform this action"
And this has been the extent of my troubleshooting. I couldn't find anyone else with this issue while searching, I can't imagine what I could have done incorrectly while setting this up, but apparently something is pissed at me ;)
Thank you so much for even taking the time to read this, the plugin is excellent, and I appreciate all the support you have provided the community.
Thanks!
