Invalid Scopes: manage_pages, publish_page

Those are valid permissions. However, your app is not able to ask those permissions from any users until you've gone through the Facebook Application review process. You can read more about the process in our recent blog post, Facebook App Review Explained .

With that said, you can test or allow your admins to see those permissions by putting your Facebook App into "Development" mode. To do so, hit the slider in the top right of your app in the Facebook Developer Area . Once in Development mode, any Facebook Admins of your app can authenticate on your site and will get that permission. The permission will 'stick' with the user even after you've made the app Live again, which is usually enough for most users of JFBConnect to avoid the full App Review process. You only need to go through App Review if you're going to ask non-admins those permissions, which isn't common.

I hope that helps, but if you need anything else, please let us know!

You'll need to delete the old channel from an earlier version of JFBConnect and recreate it. That should hopefully get you going. Facebook changed the permissions required for posting. JFBConnect updated to use the new permissions, but there are cases where older versions of JFBConnect that used the previous permissions/scope do not get updated properly when upgrading.

If deleting the channel doesn't work, then you need to go one step further by deleting the channel and then deleting your user from the Usermap area (not the actual Joomla user!) and re-authenticate on the front -end. Then you can recreate the channel again from scratch and your user will be requested the proper permissions.

I hope that helps, but if you need anything else, please let us know!
