The 4 most common causes of that Bad Request Token are:
1. Your Twitter Application wasn't set up properly
2. You didn't copy the API Key and Secret properly to JFBConnect
3. Your Twitter API and Secret Keys may need to be regenerated in your Twitter application. This may be done inside the Twitter Development area for your app.
4. Your server time is incorrect (uncommon)
I would suggest trying the above, and if that fails, going through step-by-step of
our Twitter Application setup guide
.
Let us know if you have any success with the above.
