Login via Twitter is telling me, that Twitter is not setup correctly, but I rechecked the options in the oneall backend. They are all correct. Is there something special on Twitter I need to consider?
FB, Linkedin and Google does work smoothly though.
1) Make sure that you have entered something (eg. http://www.example.com) in the field Callback URL 2) Make sure that you have ticked Allow this application to be used to Sign in with Twitter
