Hi I have installed this plugin. And almost everything is running as it should but....
Every time some one likes to login/ register with Facebook they got this error:
Unable to load the registration form for this ID. You may have previously blocked this app on Facebook. Go to your Facebook privacy settings to unblock this app. (Error: Invalid 'client_id'.)
I have unblocked it myself and that worked fine. But why does this happen and have I made something wrong i apps for Facebook?
Hope someone can help with this. Sorry for my bad English
