[Twitter Addon] Could not be enabled because it generated a fatal error*

edited February 2011 in Vanilla 2.0 - 2.8
Fatal error: Cannot redeclare class OAuthException in /[public root directory snipped for safety]/library/vendors/oauth/OAuth.php on line 8
Happens on both Chrome Stable and Internet Explorer 9 Beta
PHP 5.2.15, MySQL 5.1.52


  • I’m not sure the root of this problem, but a quick-and-dirty fix would be to make the following change:


    if (!class_exists('OAuthException')) {
      class OAuthException extends Exception {
        // pass
  • yes that is quick and definitely dirty, don't do it. This is merely asking the program not to check but will cause more problems.
