error 0 on login with twitter

The 3 most common causes of that issue are:

* Your Twitter Application wasn't set up properly
* You didn't copy the API Key and Secret properly to JFBConnect
* Your server time is incorrect (not common)

Please verify #1 and #2 and go through our Twitter Application Setup Guide again.

You can also try in the developer area for the Twitter App to regenerate the API and Secret Keys, put the new values into JFBConnect and see if that helps.

Thanks for letting us know. I've seen that help other users in the future, but I'm not sure why it fixes the issue honestly Let us know if you run into this again.

Marcos,
Thanks for your feedback. We haven't done much testing with that Callback Locking option, but I wouldn't think that would give an error 0 when trying to login. We'll have to test further, but appreciate letting us know your findings in case others run into the same problem.

Thanks,
Alex
