Twitter not working on HybridAuth

Question

I have uploaded the website on pantheon. Users aren't able to login by using twitter provider on my website. I'm using the HybridAuth module. When I try to login, it shows this error

Fatal error: Cannot redeclare class OAuthException in /srv/bindings/6349f4db8cd54067ae94453f36acb8ec/code/sites/all/libraries/hybridauth/hybridauth/Hybrid/thirdparty/OAuth/OAuth.php on line 11

How do I fix this issue? I have a Facebook login as well and it works. And both the logins work on local host.
