I suspect that error coming from jfbconnect because you sign in via jfbconnect social button, you have to consult with jfbconnect developer regarding this.

Based on what we received our customer report, Easysocial build-in Twitter login also having the issue is because now Twitter forced user to add the correct callback url into apps in order work correct.

If you use Easysocial build-in Twitter login, you can temporary use this method to get the correct callback url https://stackideas.com/forums/twitter-sign-in-stopped-working#reply-417896

If you use jfbconnect, you have to consult with their developer regarding this.
