Provide callback URL in settings form

Hi!

Please provide more info on when this happens. Are you being redirected to Twitter for authentication?

In that case, it might be failing somewhere in the try block in redirectToTwitter. Maybe the SDK library is not beind loaded. Make sure you have the directory abraham/twitteroauth inside the vendor folder of your root directory.

It seems like this error is caused because of these changes in Twitter API. Make sure you include the correct callback url.

Did this fix your issue?

I also having the same issue,
All keys are correct and also have abraham/twitteroauth package in my vendor directory.

It didn't redirect me to twitter for authentication but simply throws below error.
"You could not be authenticated, please contact the administrator."

Hi all

There is no notification in backend to add callback url for twitter app however after adding callback url ( https://domain.com/user/login/twitter/callback ) to twitter app resolve my issue.

As noted in #7, this requirement is new in Twitter. I'll create a patch to provide the callback url in the settings form as we do it in other implementers.
