Hi Sterling,
I’m having the same issue related in this post from some months ago.
To reiterate the issue here, I can’t login to twitter in the user profile page, when clicking the signin button, it returned this url: “https://api.twitter.com/oauth/authorize?oauth_token=” (the url ended with the “=” sign) and twitter returned an error message:
Woah there!
This page is no longer valid. It looks like someone already used the token information you provided. Please return to the site that sent you to this page and try again … it was probably an honest mistake.
Any help would be appreciated.
Patrick
