Trying to post to Twitter and after I create a node that is supposed to tweet, I get a blank white page. I checked the server error log and found this error:
PHP Fatal error: Cannot redeclare class OAuthSignatureMethod_HMAC_SHA1 in
/var/www/html/newsome/sites/all/modules/oauth/lib/OAuth.php on line 120
The node saves, but clearly chokes on trying to tweet.
