I followed your instruction till the end of the process, but when I click on the button "Sign in with Twitter" I get a popup with an error message telling me that the token is not valid.
Maybe it's because it's already used by JomSocial ?
It's most likely because your Twitter app is not configured correctly. Perhaps if you can provide me with your Twitter access, I could help you login and check the app that you have created
I've disabled the following options from your twitter apps, http://screencast.com/t/cNGzUj4VtRrM and the sign in is now working correctly as it should. Please have a look.
You are most welcome. Glad to hear that your issue has been resolved now.
As a gentle reminder, kindly start a new thread if you have any other issue in the future so it will be easier for us to manage your inquiry. I will lock and mark this thread as resolved.
